Default for global (user) git ignore file
C git has a default for git config core.excludesfile: "Its default
value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either
not set or empty, $HOME/.config/git/ignore is used instead." [1]
Implement this in the WorkingTreeIterator$RootIgnoreNode.
To make this testable, mock the "user.home" directory for all JGit
tests, otherwise tests might pick up a real user's git ignore file.
Also ensure that JGit code always reads "user.home" via the
SystemReader.

Fix all Javadoc warnings and fail on them
This fixes all the javadoc warnings, stops ignoring doclint 'missing'
category and fails the build on javadoc warnings for public and
protected classes and class members.
Since javadoc doesn't allow access specifiers when specifying doclint
configuration we cannot set `-Xdoclint:all,-missing/private`
hence there is no simple way to skip private elements from doclint.
Therefore we check javadoc using the Eclipse Java compiler
(which is used by default) and javadoc configuration in
`.settings/org.eclipse.jdt.core.prefs` files.
This allows more fine grained configuration.
We can reconsider this when javadoc starts supporting access specifiers
in the doclint configuration.
Below are detailled explanations for most modifications.
@inheritDoc
===========
doclint complains about explicits `{@inheritDoc}` when the parent does
not have any documentation. As far as I can tell, javadoc defaults to
inherit comments and should only be used when one wants to append extra
documentation from the parent. Given the parent has no documentation,
remove those usages which doclint complains about.
In some case I have moved up the documentation from the concrete class
up to the abstract class.
Remove `{@inheritDoc}` on overriden methods which don't add additional
documentation since javadoc defaults to inherit javadoc of overridden
methods.
@value to @link
===============
In PackConfig, DEFAULT_SEARCH_FOR_REUSE_TIMEOUT and similar are forged
from Integer.MAX_VALUE and are thus not considered constants (I guess
cause the value would depends on the platform). Replace it with a link
to `Integer.MAX_VALUE`.
In `StringUtils.toBoolean`, @value was used to refer to the
`stringValue` parameter. I have replaced it with `{@code stringValue}`.
{@link <url>} to <a>
====================
@link does not support being given an external URL. Replaces them with
HTML `<a>`.
@since: being invalid
=====================
org.eclipse.jgit/src/org/eclipse/jgit/util/Equality.java has an invalid
tag `@since: ` due to the extra `:`. Javadoc does not complain about it
with version 11.0.18+10 but does with 11.0.19.7. It is invalid
regardless.
invalid HTML syntax
===================
- javadoc doesn't allow <br/>, <p/> and </p> anymore, use <br> and <p>
instead
- replace <tt>code</tt> by {@code code}
- <table> tags don't allow summary attribute, specify caption as
<caption>caption</caption> to fix this
doclint visibility issue
========================
In the private abstract classes `BaseDirCacheEditor` and
`BasePackConnection` links to other methods in the abstract class are
inherited in the public subclasses but doclint gets confused and
considers them unreachable. The HTML documentation for the sub classes
shows the relative links in the sub classes, so it is all correct. It
must be a bug somewhere in javadoc.
Mute those warnings with: @SuppressWarnings("doclint:missing")
Misc
====
Replace `<` and `>` with HTML encoded entities (`< and `>`).
In `SshConstants` I went enclosing a serie of -> arrows in @literal.
Additional tags
===============
Configure maven-javad0c-plugin to allow the following additional tags
defined in https://openjdk.org/jeps/8068562:
- apiNote
- implSpec
- implNote
Missing javadoc
===============

Reason for revert: This change was based on the false claim that the
packedrefs file lock is held while the CAS is being done, but it is
actually released before the CAS (the in memory lock is still held,
however that does not prevent external actors from updating the
packedrefs files and then another thread from subsequently re-reading it
and updating the in memory packedRefList). Although reverting this
change can cause the CAS to fail, it should not actually matter since
the failure would indicate that another thread has already updated the
in memory packedRefList to either the same version this thread was
trying to update it too, or to a more recent version. Either way,
failing the CAS is then appropriate and should not be problematic.
Although this change reverts the code in the RefDirectory class, it
keeps the "improvements" to the test so that it continues to pass
reliably. The reason for the quotes around the word "improvements" is
because I believe the test alteration actually dramatically changes the
intent of the test, and that the original intent of the test is
untestable with the GC and RefDirectory classes as is.

AddCommand: ability to switch off renormalization
JGit's AddCommand always renormalizes tracked files. C git does so only
on git add --renormalize. Especially for git add . and the JGit
equivalent git.add().addFilepattern(".").call() this can make a big
difference if there are many files, or large files.
Add a "renormalize" option to AddCommand. To maintain compatibility with
existing uses, this option is "true" by default, and the behavior of
AddCommand is as it has always been in JGit.
If set to "false", use an IndexDiffFilter (in addition to a path filter,
if any). This skips any unchanged files (that are not racily clean) from
content checks. Note that changes in CRLF settings or in filters will be
ignored for such files if renormalize == false.
Add the "--renormalize" option to the Add command in the JGit command
line program. For the command-line program, the default is as in C git:
renormalize is off by default and enabled only if the option is given.
Note that --renormalize implies --update in the command line program, as
in C git. In AddCommand, the two settings are independent.
Additionally, avoid opening input streams unnecessarily in
WorkingTreeIterator.getEntryContentLength() and fix some bogus
indentation.
Add a simple test that adds 1000 files of 10kB in 10 directories twice
and that fails if the second invocation (without any changes) with
renormalize=false is not significantly faster.

PackReverseIndexWriter: write out version 1 reverse index file
The reverse index for a pack is used to quickly find an object's
position in the pack's forward index based on that object's pack offset.
It is currently computed from the forward index by sorting the index
entries by the corresponding pack offset. This computation uses
bucket sort with insertion sort, which has an average runtime of
O(n log n) and worst case runtime of O(n^2); and memory usage of
3*size(int)*n because it maintains 3 int arrays, even after sorting is
completed. The computation must be performed every time that the reverse
index object is created in memory.
In contrast, Cgit persists a pack reverse index file to avoid
recomputing the reverse index ordering every time that it is needed.
Instead they write a file with format
https://git-scm.com/docs/pack-format#_pack_rev_files_have_the_format
which can later be read and parsed into an in-memory reverse index each
time it is needed.
Introduce these reverse index files to JGit. PackReverseIndexWriter
writes out a reverse index file to be read later when needed. Subclass
PackReverseIndexWriterV1 writes a file with the official version 1
format.
To avoid temporarily allocating an Integer collection while sorting and
writing out the contents, using memory 4*size(Integer)*n, use an
IntList and its #sort method, which uses quicksort.
