When using an existing git repository to cache the perforce import we don't
fetch the branch mapping from perforce as that is a slow operation. However
the origin repository may not be fully up-to-date and therefore it may be
necessary to import more changes directly from Perforce.
Such a direct import needs self.knownBranches to be set up though, so
initialize it from the existing p4/* git branches.

This changeset takes advantage of the new parseDiffTreeEntry(...) function to
detect changes to the execute bit in the git repository. During submit, git-p4
now looks for changes to the executable bit and if it finds them it "reopens"
the file in perforce, which allows it to change the file type.
The logic for adding the executable bit in perforce is straightforward: the +x
modifier can be used. Removing the executable bit in perforce requires that the
entire filetype be redefined (there is no way to join remove the bit with a -x
modifier, for example). This changeset includes logic to remove the executable
bit from the full file type while preserving the base file type and other
modifiers.

The current git-p4 implementation does support file renames. However, because
it does not use the "p4 integrate" command, the history for the renamed file is
not linked to the new file.
This changeset adds support for perforce renames with the integrate command.
Currently this feature is only enabled when calling git-p4 submit with the -M
option. This is intended to look and behave similar to the "detect renames"
feature of other git commands.
The following sequence is used for renamed files:
p4 integrate -Dt x x'
p4 edit x'
rm x'
git apply
p4 delete x
By default, perforce will not allow an integration with a target file that has
been deleted. That is, if x' in the example above is the name of a previously
deleted file then perforce will fail the integrate. The -Dt option tells
perforce to allow the target of integrate to be a previously deleted file.

Given that git uses 'commit', git-p4's 'sumbit' was a bit confusing at times;
often making me do 'git submit' and 'git-p4 commit' instead.

If a change in a p4 "branch" appears that hasn't seen any previous commit and
that has a known branch mapping we now try to import it properly. First we
find the p4 change of the source branch that the new p4 branch is based on. Then
we using git rev-list --bisect to locate the corresponding git commit to that change.
Finally we import all changes in the new p4 branch up to the current change and resume
with the regular import.

After a clone with "git clone" of a repository the p4 branches are only in remotes/origin/p4/* and not in remotes/p4/*.
Separate the code for detection and creation out of the P4Sync command class into standalone methods and use them
from the P4Branches command.

When performing a git-p4 clone operation on a Perforce repository,
where the changelists change in order of magnitude (e.g. 100 to 1000),
the set of changes to import from is not sorted properly. This is
because the data in the list is strings not integers. The other place
where this is done already converts the value to an integer, so it is
not affected.

Don't use git name-rev to locate the upstream git-p4 branch for rebase and submit but instead locate the branch by comparing the depot paths.
name-rev may produce results like wrongbranch~12 as it uses the first match.

A perforce command with all the files in the repo is generated to get
all the file content.
Here is a patch to break it into multiple successive perforce command
who uses 4K of parameter max, and collect the output for later.
It works, but not for big depos, because the whole perforce depo
content is stored in memory in P4Sync.run(), and it looks like mine is
bigger than 2 Gigs, so I had to kill the process.
