Hi,

this is quite ready $TST_ALL_FILESYSTEMS (i.e. support for LTP shell API
to run test on all available filesystems, equivalent of .all_filesystems
in C API). It's used in NFS tests, where I have questions (RFC).

As it uses testcases/lib/tst_supported_fs.c binary it supports the same
features as C API:
* detect supported filesystems
* run only on single filesystem with $LTP_SINGLE_FS_TYPE (debugging)

825e10a91 ("Skip tmpfs in all-filesystem shell tests")


TODO API:
* filtering filesystems when test does not run on certain filesystem
* (i.e. nfs01.sh on vfat) with $TST_SKIP_FILESYSTEMS (equivalent of
  skip_filesystems variable in C API)
* testcases/lib/tst_supported_fs.c skips tmpfs by default since
  825e10a91 ("Skip tmpfs in all-filesystem shell tests"). After
  implementing $TST_SKIP_FILESYSTEMS it could be removed.

TODO NFS tests:
* Do not require restart NFS server (otherwise legacy testcases/lib/daemonlib.sh
  would have to be used)

Comments are welcome.

Code is also at: https://github.com/pevik/ltp/tree/shell/all_filesystems.v2

Kind regards,
Petr
