convert git-annex branch access to ByteStrings and Builders
Most of the individual logs are not converted yet, only presense logs
have an efficient ByteString Builder implemented so far. The rest
convert to and from String.

dropdead per-remote metadata
Had to refactor pure code into separate modules so it is accessible
inside Annex.Branch.Transitions.

Added GIT_ANNEX_VECTOR_CLOCK environment variable
Can be used to override the default timestamps used in log files in the
git-annex branch. This is a dangerous environment variable; use with
caution.

Note that this only affects writing to the logs on the git-annex branch.
It is not used for metadata in git commits (other env vars can be set for
that).

There are many other places where timestamps are still used, that don't
get committed to git, but do touch disk. Including regular timestamps
of files, and timestamps embedded in some files in .git/annex/, including
the last fsck timestamp and timestamps in transfer log files.

A good way to find such things in git-annex is to get for getPOSIXTime and
getCurrentTime, although some of the results are of course false positives
that never hit disk (unless git-annex gets swapped out..)

So this commit does NOT necessarily make git-annex comply with some HIPPA
privacy regulations; it's up to the user to determine if they can use it in
a way compliant with such regulations.

Benchmarking: It takes 0.00114 milliseconds to call getEnv
"GIT_ANNEX_VECTOR_CLOCK" when that env var is not set. So, 100 thousand log
files can be written with an added overhead of only 0.114 seconds. That
should be by far swamped by the actual overhead of writing the log files
and making the commit containing them.

Split lines in the git-annex branch on \r as well as \n, to deal with \r\n terminated lines written by some versions of git-annex on Windows.
This fixes strange displays in some cases, including whereis showing
many duplicate locations, and showing more total copies than actually
exist.

It's unknown if that lead to data loss when eg, dropping. At the moment,
it seems unlikely it could, since the UUID with \r's appended is not the
same as a UUID without, and so no remote matches it.

It's also unknown if \r's can leak in on windows, perhaps when merging the
git-annex branch.

6cf62a9bde support time-1.5.0
This no longer uses old-locale's defaultTimeLocale, but provides one
of its own.

Factored out a Logs.TimeStamp.

9fd95d9025 indent with tabs not spaces
Found these with:
git grep "^  " $(find -type  f -name \*.hs) |grep -v ':  where'

Unfortunately there is some inline hamlet that cannot use tabs for
indentation.

Also, Assistant/WebApp/Bootstrap3.hs is a copy of a module and so I'm
leaving it as-is.

b40df4f0d0 reorganize numcopies code (no behavior changes)
Move stuff into Logs.NumCopies. Add a NumCopies newtype.

Better names for various serialization classes that are specific to one
thing or another.

d66535f065 global numcopies setting
* numcopies: New command, sets global numcopies value that is seen by all
  clones of a repository.
* The annex.numcopies git config setting is deprecated. Once the numcopies
  command is used to set the global number of copies, any annex.numcopies
  git configs will be ignored.
* assistant: Make the prefs page set the global numcopies.

This global numcopies setting is needed to let preferred content
expressions operate on numcopies.

It's also convenient, because typically if you want git-annex to preserve N
copies of files in a repo, you want it to do that no matter which repo it's
running in. Making it global avoids needing to warn the user about gotchas
involving inconsistent annex.numcopies settings.
(See changes to doc/numcopies.mdwn.)

Added a new variety of git-annex branch log file, that holds only 1 value.
Will probably be useful for other stuff later.
