There's been some subtle API changes that may be useful to detect via
`MIN_VERSION_unix(2,7,2)`, consequently perform a minor version bump
relative to the last release.

Since the primary purpose of `tcdrain(3)` is to block it makes much more
sense to use a `safe` FFI import.

This follows the scheme suggested in #24

This fixes #55

This attempts a simpler and hopefully more robust test for `fdatasync(2)`

See 94d8824b / #42 for the previous attempt.

This hopefully addresses #52 in a better way than #53

This all started in e968172c which tried
to get rid of redundant import warnings. But we should rather err on
having to tolerate a few warnings on exotic configurations rather than
breaking a build...

This hopefully fixes #36

This patch does not modify the `BaudRate` structure but rather causes
some functions taking a `BaudRate` to throw exceptions on systems which
don't provide `B57600` and/or `B115200`. I'm not totally happy with this
patch yet, but this unbreaks compilation on platforms which don't define
at least of these constants.

This fixes #51

This fixes #50

It seems these two signals have not been working since at least
2009. Detection of these signals seems to have never been added to
the configure.ac script and the code guarded by #ifdef then bit-rotted
(the idiom used to handle these signals seems to have been abandoned
for something simpler/better in 2009). This fix simply handles these
signals the same way the other signals are handled in
System/Posix/Signals.hsc.

Closes #30 and #31

This adds two new functions in `System.Posix.Unistd`

 - `fileAdvise` (aka `posix_fadvise(2)`), and
 - `fileAllocate` (aka `posix_fallocate(2)`)

This is based in part on #7 and has been heavily refactored from its
original patch submission by Ricardo Catalinas Jiménez.

This also bumps version to 2.7.1.0 as a minor version bump is now needed.

If `PATH` environment variable contains non directory component,
`__hsunix_execvpe()` failed by `ENOTDIR`.

This fixes #11 for all platforms.

This makes sure we pick up the LFS version of `truncate` in case `off_t`
is affected by CPP defines such as `_FILE_OFFSET_BITS`.

This fixes the FFI imports to use the proper `CLong` type over the
previous incorrect `COff` type, as using the wrong argument type can
cause problems when the `long` and `off_t` types have different size.

Historic note from the manual page:

  In glibc up to version 2.1.1, the return type of telldir() was off_t.
  POSIX.1-2001 specifies long, and this is the type used since glibc
  2.1.2 (released in 1999).

This patch fixes getGroupEntryForID and getGroupEntryForName on Solaris
The issue on Solaris is that it defines both required getgrgid_r
and getgrnam_r functions as CPP macros which depending on configuration
are mapped to real function implementations with different names.
The issue is solved by using C API calling convention instead of platform
C ABI calling convention.

This extends `System.Posix.Files.`access` to map EROFS & ETXTBSY to
mean permission denied just like EACCESS.
