Fix ResolveMerger when files should be replaced by folders
When during Merge for a certain path OURS & BASE contains a file and
THEIRS contains a folder there was a bug in JGit leading to unnecessary
conflicts. This commit fixes it and adds a test for this situation.

According to [1] leading spaces are allowed in ignore rules and trailing
spaces are allowed too if they are escaped via backslash.

Allow leading literal '#' and '!' in ignore rules if they are escaped
According to [1] backslash can escape leading special characters '#' and
'!' in ignore rules, so that they are treated literally.

Consider only escaping backslash for regular expressions in ignore rules
While checking if we should consider an ignore rule without '[]'
brackets as a regular expression, check if the backslash escapes one of
the glob special characters '?', '*', '[', '\\'. If not, backslash is
not a part of a regex and should be treated literally.

BaseReceivePack: Don't throw from getPushCertificate()
Rather than lazily parsing the push in this method, parse it at the
end of recvCommands(), which already contains the necessary try/catch
for handling this error. This allows later callers to avoid having to
handle this condition superfluously.

Consider a BatchRefUpdate produced by Gerrit Code Review, where the
original command pushed over the wire might refer to
"refs/for/master", but that command is ignored and replaced with some
additional commands like creating "refs/changes/34/1234/1". We do not
want to store the cert in "refs/for/master@{cert}", since that may
lead someone looking to the ref to the incorrect conclusion that that
ref exists.
Add a separate put method that takes a collection of commands, and
only stores certs on those refs that have a matching command in the
cert.

Inspired by a proposal from gitolite[1], where we store a file in
a tree for each ref name, and the contents of the file is the latest
push cert to affect that ref.
The main modification from that proposal (other than lacking the
out-of-git batching) is to append "@{cert}" to filenames, which allows
storing certificates for both refs/foo and refs/foo/bar. Those
refnames cannot coexist at the same time in a repository, but we do
not want to discard the push certificate responsible for deleting the
ref, which we would have to do if refs/foo in the push cert tree
changed from a tree to a blob.
The "@{cert}" syntax is at least somewhat consistent with
gitrevisions(7) wherein @{...} describe operators on ref names.
As we cannot (currently) atomically update the push cert ref with the
refs that were updated, this operation is inherently racy. Kick the can
down the road by pushing this burden on callers.

PushCertificateParser: Add method for parsing from a stream
We intend to store received push certificates somewhere, like a
particular ref in the repository in question. For reading data back
out, it will be useful to read push certificates (without pkt-line
framing) in a streaming fashion.
Change-Id: I70de313b1ae463407b69505caee63e8f4e057ed4
Discussion on the git mailing list has concluded[1] that the intended
behavior for all (non-sideband) portions of the receive-pack protocol
is for trailing LFs in pkt-lines to be optional. Go back to using
PacketLineIn#readString() everywhere.
For push certificates specifically, we agreed that the payload signed
by the client is always concatenated with LFs even though the client
MAY omit LFs when framing the certificate for the wire. This is still
reflected in the implementation of PushCertificate#toText().

Throw InvalidObjectIdException from ObjectId.fromString("tooshort")
ObjectId.fromString already throws InvalidObjectIdException for most
malformed object ids, but for this kind it previously threw
IllegalArgumentException. Since InvalidObjectIdException is a child of
IllegalArgumentException, callers that catch IllegalArgumentException
will continue to work.

Avoid double-colon in InvalidObjectIdException description
The invalidId message in JGitText and the asAscii bad id both contain a
colon, so the resulting message would say
Invalid id: : a78987c98798ufa
Fix it by keeping the colon in the translated message and not adding
another colon programmatically.
Noticed by code inspection.

Add a separate type for the identity in a push certificate
These differ subtly from a PersonIdent, because they can contain
anything that is a valid User ID passed to gpg --local-user. Upstream
git push --signed will just take the configuration value from
user.signingkey and pass that verbatim in both --local-user and the
pusher field of the certificate. This does not necessarily contain an
email address, which means the parsing implementation ends up being
substantially different from RawParseUtils.parsePersonIdent.
Nonetheless, we try hard to match PersonIdent behavior in
questionable cases.

The default behavior is to read a repository's signed push
configuration from that repo's config file, but this is not very
flexible when it comes to managing groups of repositories (e.g. with
Gerrit). Allow callers to override the configuration using a POJO.

BaseReceivePack: fix reading cert lines in command loop
Add a missing continues to prevent falling through to the command
parsing section. The first continue happens when the command list is
empty, so change the condition to see whether we have read the first
line, rather than any commands.
Fix comparison to BEGIN_SIGNATURE to use raw line with newline.

a85e817d is a slightly breaking API change to classes that were
technically public and technically released in 4.0. However, it is
highly unlikely that people were actually depending on public behavior,
since there were no public methods to create PushCertificates with
anything other than null field values, or a PushCertificateParser that
did anything other than infinite loop or throw exceptions when reading.

Introduce PostUploadHook to replace UploadPackLogger
UploadPackLogger is incorrectly named--it can be used to trigger any
post upload action, such as GC/compaction. This change introduces
PostUploadHook/PostUploadHookChain to replace
UploadPackLogger/UploadPackLoggerChain and deprecates the latter.
It also introduces PackStatistics as a replacement for
PackWriter.Statistics, since the latter is not public API.
It changes PackWriter to use PackStatistics and reimplements
PackWriter.Statistics to delegate to PackStatistics.
