All the produced binary are now named `gkfs_*` instead of `ifs_*`

Add support for `AT_FDCWD` in some intercepted functions

Closes #88

See merge request zdvresearch_bsc/adafs!127

Some of the glibc intercepted functions,
that are accepting the directory file descriptor,
where still using legacy code to relativize the input path.

Disable interception during library shutdown

See merge request zdvresearch_bsc/adafs!114

If we intercept function during shutdown we could try to access the
internal file map that has been already freed.

This woun't affect performance at runtime since we are always checking
only one boolean flags on every interception as before.

On the other hand should sppedup the shutdown of the library, because we
disable the interception of glibc library call before performing the
shutdown routines.

Update mercury and drop margo handles patch

See merge request zdvresearch_bsc/adafs!125

Since mercury fixed the issue on their code [1], we can drop the
temporary patch we were using to avoid handles reset.

Due to the mercury fix The follwing two issues have been solved:
 - Mercury: https://github.com/mercury-hpc/mercury/issues/272
 - Margo: https://xgitlab.cels.anl.gov/sds/margo/issues/47

[1]: https://github.com/mercury-hpc/mercury/commit/9512b8b04c265645f95fd99f3b9c015e836c0347

improved statfs and statvfs

See merge request zdvresearch_bsc/adafs!110

 - improved statfs system call
 - intercepted statvfs library call

Both of the above function now report the aggregated real size
of all the data-nodes.

You can test this with `df "/tmp/gekkofs_mountpoint"` command

mercury changed again its interface.
Before was `ofi+sockets://fi_sockaddr_in://<IP>:<port>` but now
it only works if we omit the intermediate protocol `ofi+sockets://<IP>:<port>`

They fixed a potential race condition:

Margo fix handle cache

Closes #85

See merge request zdvresearch_bsc/adafs!116

See: https://xgitlab.cels.anl.gov/sds/margo/issues/47

Workaround must be reverted once fixed.

bugfix: check empty string on has_trailing_slash

Closes #84

See merge request zdvresearch_bsc/adafs!113

Canonicalize input paths

Closes #81

See merge request zdvresearch_bsc/adafs!112

Changes have been merged upstream [1] with commit `acb8c296a694d7e3e06756e7a102a9d1c92df0c8`.
There is no more need to patch margo to expose enanched init function.

[1]: https://xgitlab.cels.anl.gov/sds/margo/merge_requests/9

since back() has undefined behaviour on empty string we need to ensure
that the string is not empty before to check the last char.

Fix access to non-existing map entry, code maintainence

Closes #83

See merge request zdvresearch_bsc/adafs!111

Paths passed as parameter to the daemon needs to be canonicalized
