statfs: make getfstype() raise OSError It's better for getfstype() function to not suppress an error. Callers can handle it as necessary. Now "hg debugfsinfo" will report OSError.

statfs: rename pygetfstype to getfstype There's no ambiguity now.

statfs: refactor inner function as a mapping from statfs to string The major difference between BSD and Linux is how to get a fstype string. Let's split the longest part of getfstype() as a pure function.

statfs: simplify handling of return value Py_BuildValue() can translate NULL pointer to None.

hghave: use util.getfstype

runtests: change local IP glob pattern from "127.0.0.1" to "$LOCALIP" This is similar to what 348b2b9da703 does. Since 636cf3f7620d has changed "127.0.0.1" to "$LOCALIP". The glob pattern needs update accordingly. It is expected to fix tests running in some BSD jails.

tags: deprecated 'repo.tag' All user are gone. We can now celebrate the removal of some extra line from the 'localrepo' class.

drawdag: use 'tagsmod.tag' instead of 'repo.tag' The former is about to be deprecated.

tags: use the 'tag' function from the 'tags' module in the 'tag' command There is No need to go through the 'repo' object method anymore.

tags: move 'repo.tag' in the 'tags' module Similar logic, pretty much nobody use this method (that creates a tag) so we move it into the 'tags' module were it belong.
