localrepo: use the path relative to "self.vfs" instead of "path" argument
As a part of migration to vfs, this patch uses "self.root", which can
be recognized as the path relative to "self.vfs", instead of "path"
argument.
This fix allows to make invocations of "util.makedirs()" and
"os.path.exists()" while ensuring repository directory in
"localrepository.__init__()" ones indirectly via vfs.
But this fix also raises issue 2528: "hg clone" with empty destination.
"path" argument is empty in many cases, so this issue can't be fixed
in the view of "localrepository.__init__()".
Before this patch, it is fixed by empty-ness check ("not name") of
exception handler in "util.makedirs()".
try:
os.mkdir(name)
except OSError, err:
if err.errno == errno.EEXIST:
return
if err.errno != errno.ENOENT or not name:
raise
This requires "localrepository.__init__()" to invoke "util.makedirs()"
with "path" instead of "self.root", because empty "path" is treated as
"current directory" and "self.root" becomes valid path.
But "hg clone" with empty destination can be detected also in
"hg.clone()" before "localrepository.__init__()" invocation, so this
patch re-fixes issue2528 by checking it in "hg.clone()".
