Without this change, '.git\HEAD' files, for examples, are sometime
read incorrectly resulting in the current branch to be reset to
"master" when running a "repo init -b xxx" on an already initialized
repository.

When starting a branch, branch.merge is set to project revision unless
the revision is a SHA1. In that case, branch.merge is set to dest_branch
if defined or manifest default revision otherwise. This special handling
allows repo upload to work when the project revision is a SHA1.
Extend the special handling to also happen when the project revision
is a tag value or a change value so that repo upload will work in those
case as well.

* Add .decode('utf-8') where needed
* Add 'b' to `open` where needed, and remove where unnecessary
Change-Id: I0f03ecf9ed1a78e3b2f15f9469deb9aaab698657
* Fix imports.
* Use python3 syntax.
* Wrap map() calls with list().
* Use list() only wherever needed.
(Thanks Conley!)
* Fix dictionary iteration methods
(s/iteritems/items/).
* Make use of sorted() in appropriate places
* Use iterators directly in the loop.
* Don't use .keys() wherever it isn't needed.
* Use sys.maxsize instead of sys.maxint
TODO:
* Make repo work fully with python3. :)
Some of this was done by the '2to3' tool [1], by
applying the needed fixes in a way that doesn't
break compatibility with python2.

When repo is trying to figure out branches the repository has by
traversing refs/heads, add exception handling for readline.

The value of the varible TRACE was copied during the import, which
happens before the --trace option can be processed. So instead we
now use a function to determine if the value is set, as the function
can be safely copied early during import.

These are not as expensive as spawning a git command, but they are
not free either. We want to keep track of how many times we wind
up calling them on any particular operation.

If the m/BRANCH ref is already pointing at the value set in the
manifest there is no reason to set it again. Leave it alone,
thus saving a full fork+exec call.

By resolving the current HEAD and the manifest revision using pure
Python, we can in the common case of "no changes" avoid a lot of
git operations and directly jump out of the local sync method.
This reduces the no-op `repo sync -l` time for Android's 114 projects
from more than 6s to under 0.8s.

Its much faster to read the refs from 114 projects when the reader
is pure Python and just doing file IO than forking 114 git commands
and parsing their output.
The reader caches refs based upon file mtimes. If any single ref
file has been modified since the last read, we re-read the entire
repository's ref namespace. This simplifies the code as we don't
need to worry about shooting down symbolic-refs, but it may cause
more IO than is necessary if only one ref gets updated.
This change drops `repo branches` in Android from 1.658s to 0.206s.
Likewise, `repo sync` improves dramatically as well.
