subrepo: calculate _relpath for hgsubrepo based on self instead of parent
Prior to 105758d1b37b, the subrelpath() (now _relpath) for hgsubrepo was
calculated by removing the root path of the outermost repo from the root path of
the subrepo. Since the root paths use platform specific separators, and the
relative path is printed by various commands, the output of these commands
require a glob (and check-code.py enforces this).
In an effort to be generic to all subrepos, 105758d1b37b started calculating
this path based on the parent repo, and then joining the subrepo path in .hgsub.
One of the tests in test-subrepo.t creates a subrepo inside a directory, so the
path being joined contained '/' instead of '\'. This made the test fail with a
'~' status, because the glob is unnecessary[1]. Removing them made the test
work, but then check-code complains. We can't just drop the check-code rule,
because sub-subrepos are still joined with '\'. Presumably the other subrepo
types have this issue as well, but there likely isn't a test with git or svn
repos inside a subdirectory.
This simply restores the exact _relpath value (and output) for hgsubrepos prior
to 105758d1b37b.

subrepo: backout 93b0e0db7929 to restore reporelpath()
The path for hgsubrepo needs to be calculated slightly differently from other
subrepo types, but can reuse this. See the next patch for details.

diff: pass the diff matcher to the copy logic
This passes the existing diff matcher instance down to the copy logic so copy
tracing can be more efficient when possible and only trace copies for matching
files.
This only actually affects forwardcopies (i.e. Given A<-B<-C<-D, it works for
'hg diff -r B -r D foo.txt', but not for 'hg diff -r D -r B foo.txt') since
backward copies require walking all histories, and not just the individual
file's.
This reduces 'hg diff -r A -r B foo.txt' time from 15s to 1s when A and B have
80,000 files different.

copies: add matcher parameter to copy logic
This allows passing a matcher down the pathcopies() stack to _forwardcopies().
This will let us add logic in a later patch to avoid tracing copies when not
necessary (like when doing hg diff -r 1 -r 2 foo.txt).

treemanifest: extract parse method from constructor
When we start to lazily load submanifests, it will be useful to be
able to create an treemanifest instance before manifest data gets
parsed into it. To prepare for this, extract the parsing code from
treemanifest's constructor to a separate method.
