statfs: change Linux feature detection
Previously we check three things: "statfs" function, "linux/magic.h" and
"sys/vfs.h" headers. But we didn't check "struct statfs" or the "f_type"
field. That means if a system has "statfs" but "struct statfs" is not
defined in the two header files we check, or defined without the "f_type"
field, the compilation will fail.
This patch combines the checks (2 headers + 1 function + 1 field) together
and sets "HAVE_LINUX_STATFS". It makes setup.py faster (less checks), and
more reliable (immutable to the issue above).

check whether HG_PENDING makes pending changes only in relatd
repositories visible to an external hook.
In "hg share" case, another transaction can't run in other
repositories sharing same source repository, because starting
transaction requires locking store of source repository.
Therefore, this test scenario ignores checking visibility of
.hg/bookmakrs.pending in repo2, which shares repo1 without bookmarks.

FYI, in contrast to above test, bmX is invisible in repo1 (= shared
src), because (1) HG_PENDING refers only repo3 and (2)
"bookmarks.pending" is written only into repo3.
