Config load should not fail on unsupported or nonexistent include path
1f86350 added initial support for include.path. Relative path and path
with tilde are not yet supported but config load was failing if one of
those 2 unsupported options was encountered. Another problem was that
config load was failing if the include.path file did not exist.
Change the behavior to be consistent with native git. Ignore unsupported
or nonexistent include.path.

Allow using JDK 7 bootclasspath when compiling JGit using Java 8
When compiling jgit using Java 8 set system property JDK_HOME to
JAVA_HOME path of JDK7 installation to compile against JDK 7 class
libraries. Otherwise jgit may hit runtime exceptions when running on
Java 7 (e.g. return type of ConcurrentHashMap.keySet() in JDK 8 class
library doesn't exist in JDK 7).
Example:
$ mvn clean install -DJDK_HOME=/.../jdk1.7.0_80.jdk/Contents/Home

RepoCommand: record manifest shallow recommendation in .gitmodules
Git core learned about the submodule.<name>.shallow option in
.gitmodules files, which is a recommendation to clone a submodule
shallow. A repo manifest may record a clone depth recommendation as
an optional field, which contains more information than a binary
shallow/nonshallow recommendation, so any attempted conversion may be
lossy. In practice the clone depth recommendation is either '1' or doesn't
exist, which is the binary behavior we have in Git core.

RepoCommand: record manifest groups as submodule labels
Git core learned about attributes in pathspecs:
pathspec: allow querying for attributes
The pathspec mechanism is extended via the new
":(attr:eol=input)pattern/to/match" syntax to filter paths so that it
requires paths to not just match the given pattern but also have the
specified attrs attached for them to be chosen.
(177161a5f7, 2016-05-20)
We intend to use these pathspec attribute patterns for submodule
grouping, similar to the grouping in repo. So the RepoCommand which
translates repo manifest files into submodules should propagate this
information along. This requires writing information to the
.gitattributes file instead of the .gitmodules file. For now we just
overwrite any existing .gitattributes file and do not care about prior
attributes set. If this becomes an issue we need to figure out how to
correctly amend the grouping information to an existing .gitattributes
file.

Better report on client side if push failed due to too large object
JGits PushCommand and BasePackPushConnection were throwing a generic
exception when the pushed pack-file was rejected by the server since it
contained too large objects. Teach JGit to better analyze the server's
response to detect this situation and throw a more specific exception.
Detect this situation by parsing the status line sent by the server.
This change only recognizes the response sent by a JGit based server.
All other servers which report such problems in a different way still
lead to a generic TransportExceptions.

Fix computation of id in WorkingTreeIterator with autocrlf and smudging
JGit failed to do checkouts when the index contained smudged entries and
autocrlf was on. In such cases the WorkingTreeIterator calculated the
SHA1 sometimes on content which was not correctly filtered. The SHA1 was
computed on content which two times went through a lf->crlf conversion.
We used to tell the treewalk whether it is a checkin or checkout
operation and always use the related filters when reading any content.
If on windows and autocrlf is true and we do a checkout operation then
we always used a lf->crlf conversion on any text content. That's not
correct. Even during a checkout we sometimes need the crlf->lf
conversion. E.g. when calculating the content-id for working-tree
content we need to use crlf->lf filtering although the overall operation
type is checkout.
Often this bug does not have effects because we seldom compute the
content-id of filesystem content during a checkout. But we do need to
know whether a file is dirty or not before we overwrite it during a
checkout. And if the index entries are smudged we don't trust the index
and compute filesystem-content-sha1's explicitly.
This caused EGit not to be able to switch branches anymore on Windows
when autocrlf was true. EGit denied the checkout because it thought
workingtree files are dirty because content-sha1 are computed on wrongly
filtered content.

Fix StashApply regarding handling of untracked files
There was a bug regarding how JGit handled untracked files when applying
a stash. Problem was that untracked files are applied by doing a merge
of HEAD and untrackedFiles commit with a merge base of the stashed HEAD.
That's wrong because the untrackedFiles commit has no parent and
contains only the untracked files. Using stashed HEAD as merge base
leads to unneccessary conflicts on files not event included in the
untrackedFiles commit.
Imagine this graph directly before you want to apply a stash which was
based on 0. You want to apply the stash on current HEAD commit 5.
5 (HEAD,master)
/
0---+
\ \
1---3 (WIP on master)
/
2 (untracked files on master)
Imagine for a specific (tracked) file f
- commit 0 contains X
- HEAD contains Y
- commit 2 (the untracked files) does not contain file f
A merge of 2 and 5 with a merge base of 0 leads to a conflict. The 5
commit wants to modify the file and the 2 commit wants to delete the
file -> conflict.
If no merge base is set then the semantic is correct.
Thanks to Bow for finding this bug and providing the test case.

GC should not pack objects only referenced by ORIG_HEAD,...
There are references which are returned by
RefDatabase.getAdditionalRefs() which are allowed to point to
non-existing objects. These refs should not save objects from being
garbage collected. Examples for these references are ORIG_HEAD,
MERGE_HEAD, FETCH_HEAD and CHERRY_PICK_HEAD. Native git will not take
these references into account when doing a gc and therefore these
references may point to non-existing objects after a gc. Teach JGit's
GC to behave the same: ignore additional refs if they don't start with
"refs/". Examples for refs returned by getAdditionalRefs() which do
start with "refs/" are the bootstrap refs when using reftree's (see
commit 115f1ad397). See also

Make sure to overwrite files when "reset --hard" detects conflicts
When performing a "reset --hard" a checkout is done. The pathes are
checked for potential checkout conflicts. But in the end for all
remaining conflicts these files are simply deleted from the working
tree. That's not the right strategy to handle checkout conflicts during
"reset --hard". Instead for every conflict we should simply checkout the
merge commit's content.
This is different from native gits behavior which reports errors when
during a "checkout --hard" a file shows up where a folder was expected.
"warning: unable to unlink d/c.txt: Not a directory"
Why it is like that in native git was asked in
http://permalink.gmane.org/gmane.comp.version-control.git/279482. Unless
it is explained why native git why this error is reported JGit should
overwrite the files.

Scan loose ref before packed in case gc about to remove the loose
Before this change, jgit used to read packed-refs before scanning
loose refs. That was not a problem if gc didn't run concurrently. When
gc did run concurrently with such refs reading, that order sometimes
broke the latter. This lead to reading an older version of a ref's
tip, which meant "losing" the real tip or commit. The specific
read-Vs-gc concurrency scenario which broke reading that way follows:
1. let ref R be in packed-refs and R' be in loose
2. jgit starts reading packed-refs
3. gc also starts its business around that very time
4. jgit still has the time to read R from packed-refs
5. as gc is not done yet updating packed-refs with R'
6. jgit then starts scanning loose refs (or is about to)
7. gc quickly ends up being done moving loose R' to packed-refs
8. so gc (quickly) removes loose refs
9. -while jgit is scanning loose refs, now gone
10. so jgit assumes no loose to consider => packed-refs winning
11. so jgit wrongfully returns R (from 4.) as the tip, instead of R'.
This fix switches the order so loose refs are scanned (secured) before
taking the time to read packed-refs. This way, knowledge of the
likelier tip is guaranteed for ref reading to return the true tip
- despite concurrent gc. If there is no loose ref to scan, jgit reads
packed-refs and lands on R' (or S), which it then returns, as
expected. The gerrit issue [1] should be solved by this fix.
