With the Python 2 to 3 migration and the type checking, we can be
fairly confident that smstr are always constructed from strings, not
bytes.
This allows the code to be simplified, as we no longer need to carry
the dual raw/unicode representation.

Python 3 was released more than 10 years ago, and support for Python 2
is going away, with many Linux distributions starting to phase it out.
This patch migrates git-arr to Python 3.
The generated output is almost exactly the same, there are some minor
differences such as HTML characters being quoted more aggresively, and
handling of paths with non-utf8 values.

This commit implements a "patch" view, with a simple plain-text
representation of a commit, that can be used as a patch file.

The default CSS is not very comfortable for markdown, as for example the
links are hidden.
This patch makes the markdown CSS tunable by wrapping it into a div, and
then adjusting the default styles to increase readability.

As an experiment, make the sections of the summary to be toggable. This
can help readability, although it's unclear if it's worth the additional
complexity and could be removed later.

Including the tree as part of the summary gives a bit more information
and provides an easy path into the tree.
It does clutter things a bit, so this is an experiment and may be
removed later.

We display the location of the repository, but the entire row is not
convenient for copy-pasting.
This patch changes the wording to "git clone" so the entire row can be
copied and pasted into a terminal.
There's a trick, because if we just changed the wording to:
<td>git clone</td> <td>https://example.com/repo</td>
that would get copied as:
git clone\thttps://example.com/repo
which does not work well when pasted into a terminal (as the \t gets
"eaten" in most cases).
So this patch changes the HTML to have a space after "clone":
<td>git clone </td> <td>https://example.com/repo</td>
and the CSS to preserve the space, so the following gets copied:
git clone \thttps://example.com/repo
which works when pasting on a terminal.

links.

This patch moves the pages to HTML5, and adds some simple meta tags and CSS media
constraints so things render better on mobile browsers, while leaving the
desktop unaffected.
It's still not ideal, though.

The page title in a root tree displays as "git >> repo >> branch >>",
which looks odd and fails to convey the fact that the page represents a
tree. Appending a '/' (for example "git >> repo >> branch >> /") makes
it more obvious that the page shows a tree, in general, and the root
tree, in particular.

For blobs in subdirectories, the page title always includes a double
slash between the final directory component and the filename (for
example, "git >> repo >> branch >> doc//readme.txt"). This is unsightly.
git-arr:blob() ensures that the directory passed to views/blob always
has a trailing slash, so we can drop the slash inserted by views/blob
between the directory and the filename.
As a side-effect, this also changes the page title for blobs in the root
directory. Instead of "git >> repo >> branch >> /readme.txt", the title
becomes "git >> repo >> branch >> readme.txt", which is slightly more
aesthetically pleasing.

Passing the branch name into the view indirectly via
Repo.new_in_branch() increases cognitive burden, thus outweighing
whatever minor convenience (if any) is gained by doing so. The code is
easier to reason about when the branch name is passed to the view
directly.

Empty (zero-length) blobs are currently rendered by 'pygments'
misleadingly as a single empty line, or, when 'pygments' is unavailable,
as "nothingness" preceding a horizontal rule. In either case, it is
somewhat difficult to glean concrete information about the blob.
Address this by instead rendering summary information about the blob: in
particular, its classification ("empty") and its size ("0 bytes"). This
is analogous to the summary information rendered for binary blobs
("binary" and size).

Although hexdump(1)-style rendering of binary blob content may reveal
some meaningful information about the data, it wastes even more storage
space than embedding the raw data itself. However, many binary files
have a "magic number" or other signature near the beginning of the file,
so it is often possible to glean useful information from just the
initial chunk of the file without having the entire content available.
Thus, limiting the rendered data to just an initial chunk saves storage
space while still potentially presenting useful information about the
binary content.

Raw binary blob content tends to look like "line noise" and is rarely,
if ever, meaningful. A hexdump(1)-style rendering (specifically,
"hexdump -C"), on the other hand, showing runs of hexadecimal byte
values along with an ASCII representation of those bytes can sometimes
reveal useful information about the data.
(A subsequent patch will add the ability to cap the amount of data
rendered in order to reduce storage space requirements.)

Binary blobs are currently rendered as raw data directly into the HTML
output, looking much like "line noise". This is rarely, if ever,
meaningful, and consumes considerable storage space since the entire raw
blob content is embedded in the generated HTML file.
Address this issue by instead emitting summary information about the
blob, such as its classification ("binary") and its size. Other
information can be added as needed.
As in Git itself, a blob is considered binary if a NUL is present in the
first ~8KB.

Historically, the 'blob' view was unconditionally handed cooked
(utf8-encoded) blob content, so embed_image_blob(), which requires raw
blob content, has been forced to reload the blob in raw form, which is
ugly and expensive. However, now that the Blob returned by Repo.blob()
is able to vend raw or cooked content, it is no longer necessary for
embed_image_blob() to reload the blob to gain access to the raw content.

Some blob representations (such as embedded images) require raw blob
content, however, the 'blob' view is unconditionally handed cooked
(utf8-encoded) content, thus representations which need raw content are
forced to reload the blob in raw form, which is ugly and expensive (due
to shelling out to git-cat-file a second time).
The ultimate goal is to eliminate the wasteful blob reloading when raw
content is needed. As a first step, introduce a Blob abstraction to be
returned by Repo.blob() rather than the cooked content. A subsequent
change will flesh out Blob, allowing it to return raw or cooked content
on demand without the client having to specify one or the other when
invoking Repo.blob().

Git branch names can be hierarchical (for example, "wip/parser/fix"),
however, git-arr does not take this into account when formulating URLs
on branch, tree, and blobs pages. These URLs are dysfunctional because
it is assumed incorrectly that a single "../" is sufficient to climb
over the branch name when computing relative paths to resources higher
in the hierarchy. This problem manifests as failure to load static
resources (stylesheet, etc.), broken links to commits on branch pages,
and malfunctioning breadcrumb trails.
Fix this problem by computing the the proper number of "../" based upon
the branch name, rather than assuming that a single "../" will work
unconditionally. (This is analogous to the treatment already given to
hierarchical pathnames in tree and blob views.)

Pagination link "next" does not respect 'max_pages', thus it incorrectly
remains enabled on the final page capped by 'max_pages'. When clicked,
the user is taken to a "404 Page not found" error page, which makes for
a poor user experience.
Fix this problem by teaching the "next" link to respect 'max_pages'.
(As a side-effect, this also causes 'serve' mode to respect 'max_pages',
which was not previously the case. This change of behavior is
appropriate since it brings 'serve' mode, which is intended primarily
for testing, more in line with 'generate' mode.)

When the number of commits on a branch page is less than
'commits_per_page', the pagination "next" link is disabled, indicating
correctly that this is the final page. However, if the number of commits
on the branch page is exactly 'commits_per_page', then the "next" link
is incorrectly enabled, even on the final page. When clicked, the user
is taken to a "404 Page not found" error page, which makes for a poor
user experience.
Fix this problem by reliably detecting when the branch page is the final
one. Do so by asking for (but not displaying) one commit more than
actually needed by the page. If the additional commit is successfully
retrieved, then another page definitely follows this one. If not
retrieved, then this is definitely the final page.
(Unfortunately, the seemingly more expedient approach of checking if the
final commit on the current page is a root commit -- has no parents --
is not a reliable indicator that this the final page since a branch may
have multiple root commits due to merging.)

When a repository has a "master" branch, a short summary of its most
recent commits is shown, followed by a horizontal rule. If there is no
"master" branch, then the commit summary is suppressed, however, the
rule is shown unconditionally, which is ugly, particularly when there
is already a rule following the web_url/git_url block. Therefore,
suppress the "master" branch horizontal rule when not needed. (This is
analogous to how the rule following the web_url/git_url block is
suppressed when that information is not shown).
