For a long time Gitea has tested PR patches using a git apply --check
method, and in fact prior to the introduction of a read-tree assisted
three-way merge in #18004, this was the only way of checking patches.
Since #18004, the git apply --check method has been a fallback method,
only used when the read-tree three-way merge method has detected a
conflict. The read-tree assisted three-way merge method is much faster
and less resource intensive method of detecting conflicts. #18004 kept
the git apply method around because it was thought possible that this
fallback might be able to rectify conflicts that the read-tree three-way
merge detected. I am not certain if this could ever be the case.
Given the uncertainty here and the now relative stability of the
read-tree method - this PR makes using this fallback optional and
disables it by default. The hope is that users will not notice any
significant difference in conflict detection and we will be able to
remove the git apply fallback in future, and/or improve the read-tree
three-way merge method to catch any conflicts that git apply method
might have been able to fix.
An additional benefit is that patch checking should be significantly
less resource intensive and much quicker.

The PR #21198 introduced a probable security vulnerability which
resulted in making all storage files be marked as executable.
This PR ensures that these are forcibly marked as non-executable.

As recognised in #21841 the rendering of plain text files is somewhat
incorrect when there are ambiguous characters as the html code is double
escaped. In fact there are several more problems here.
We have a residual isRenderedHTML which is actually simply escaping the
file - not rendering it. This is badly named and gives the wrong
impression.
There is also unusual behaviour whether the file is called a Readme or
not and there is no way to get to the source code if the file is called
README.
In reality what should happen is different depending on whether the file
is being rendered a README at the bottom of the directory view or not.
1. If it is rendered as a README on a directory - it should simply be
escaped and rendered as `<pre>` text.
2. If it is rendered as a file then it should be rendered as source
code.
This PR therefore does:
1. Rename IsRenderedHTML to IsPlainText
2. Readme files rendered at the bottom of the directory are rendered
without line numbers
3. Otherwise plain text files are rendered as source code.
Replace #21841

This fixes a bug where, when searching unadopted repositories, active
repositories will be listed as well. This is because the size of the
array of repository names to check is larger by one than the
`IterateBufferSize`.
For an `IterateBufferSize` of 50, the original code will pass 51
repository names but set the query to `LIMIT 50`. If all repositories in
the query are active (i.e. not unadopted) one of them will be omitted
from the result. Due to the `ORDER BY` clause it will be the oldest (or
least recently modified) one.
Bug found in 1.17.3.

The recent PR adding orphaned checks to the LFS storage is not
sufficient to completely GC LFS, as it is possible for LFSMetaObjects to
remain associated with repos but still need to be garbage collected.
Imagine a situation where a branch is uploaded containing LFS files but
that branch is later completely deleted. The LFSMetaObjects will remain
associated with the Repository but the Repository will no longer contain
any pointers to the object.
This PR adds a second doctor command to perform a full GC.

Moved files in a patch will result in git apply returning:
```
error: {filename}: No such file or directory
```
This wasn't handled by the git apply patch code. This PR adds handling
for this.

Gitea will attempt to lookup its location using LookPath however, this
fails on cmd.exe if gitea is in the current working directory.
exec.LookPath will return an exec.ErrDot error which we can test for and
then simply using filepath.Abs(os.Args[0]) to absolute gitea against the
current working directory.
