This PR continues the work in #17125 by progressively ensuring that git
commands run within the request context.
This now means that the if there is a git repo already open in the context it will be used instead of reopening it.

Fix #17514
Given the comments I've adjusted this somewhat. The numbers of characters detected are increased and include things like the use of U+300 to make à instead of à and non-breaking spaces.
There is a button which can be used to escape the content to show it.

* Allow Loading of Diffs that are too large
This PR allows the loading of diffs that are suppressed because the file
is too large. It does not handle diffs of files which have lines which
are too long.

Unfortunately due to a misread on my behalf I missed that git diff only learned
--skip-to in version 2.31.0. Thus this functionality was not working on older versions
of git.
This PR adds a handler that simply allows for us to skip reading the diffs until
we find the correct file to skip to.

* CutDiffAroundLine makes the incorrect assumption that `---` and `+++` always represent part of the header of a diff.
This PR adds a flag to its parsing to prevent this problem and adds a streaming parsing technique to CutDiffAroundLine using an io.pipe instead of just sending data to an unbounded buffer.

Gitea runs diff on highlighted code fragment for each line in order to provide
code highlight diffs. Unfortunately this diff algorithm is not aware that span tags
and entities are atomic and cannot be split.
The current fixup code makes some attempt to fix these broken tags however, it cannot
handle situations where a tag is split over multiple blocks.
This PR provides a more algorithmic fixup mechanism whereby spans and entities are
completely coalesced into their respective blocks.
This may result in a incompletely reduced diff but - it will definitely prevent the
broken entities and spans that are currently possible.
As a result of this fixup several inconsistencies were discovered in our testcases
and these were also fixed.

* Alternative fix for HTML diff entity split
This commit both reverts PR #13357 and uses the exiting implementation alredy used for spans to fix the same issue. That PR duplicates most of logic that is already present elsewhere and still was failing for some cases. This should be simpler as it uses the existing logic that already works for <span>s being split apart.
Added both test cases as well.

* Fix diff skipping lines
ParsePatch previously just skipped all lines that start with "+++ " or "--- "
and makes no attempt to see these lines in context.
This PR rewrites ParsePatch to pay attention to context and position
within a patch, ensuring that --- and +++ are only skipped if
appropriate.
This PR also fixes several issues with incomplete files.

* Finally fix diff names
#12771 attempted to fix diff by avoiding the git diff line as
it is possible to have an ambiguous line here.
#12254 attempted to fix diff by assuming that names would quoted
if they needed to be and if one was quoted then both would be.
Both of these were wrong.
I have now discovered `--src-prefix` and `--dst-prefix` which
means that we can set this in such a way to force the git diff
to always be unambiguous.
Therefore this PR rollsback most of the changes in #12771 and
uses these options to fix this.

* Fix Syntax highlight for token change in added/deleted code
For diffs we first syntax highlight the before and after line then use a 3rd party diff library to find the difference in them and create a substring based on that, which we then highlight a 2nd time to show the specific difference within a line that has changed. In a specific case if the diffrence also changes the chroma class it will split in the middle of the attr and cause broken HTML:
```
<span class="nx">oldtext<span>
<span class="k">var newtext<span>
```
Will then split on
```
<span class="
```
Where the difference starts, and produce something broken like:
```
<span class="<span class="removed-code">nx"oldtext</span></span
```
Fix that by detecting when it happens and putting the HTML back together properly before highlighting the added/deleted code.
