Currently the xfstest builds do not have any automatic dependency
calculations. It relies on a separate make depend run to build or
update dependency information. It also relies on an external
makedepend binary. If that binary does not exist, the dependencies
do not get calculated.
To remove the dependency on makedepend, gcc can be used instead as
it has a command to generate dependency information. This patch
changes the dependency rule building to use gcc.
In case anyone uses an old (several years) gcc compiler or a
compiler that doesn't support gcc compatible dependency generation,
a new configure check is added to turn off dependency checking so
builds can still be done.
To use the dependencies automatically, we need to use a special
include makefile directive to include the build dependencies into
the current makefile. Essentially once the dependencies are
calculated, they can be included into the makefile and make will
recalculate the build dependencies automatically based on that
information.
Hence we get a build that automatically calculates and keeps
dependencies up to date without dependence on any external tools.

tempnam() generates a compiler warning as a dangerous function.
This code doesn't care about security issues with tempnam, so
remove it and just manually build the filenames without the
randomness of tempnam.

Remove explicit target-per-file rules in the subdirectories being
built and replace them with target based rules using the buildrules
hooks for doing this. This results in the makefiles being simpler,
smaller and more consistent. It does mean that all binaries are
linked against the common set of libraries but this does not cause
any harm.
This patch does not address the dmapi subdirectory of the xfstests
build system.

Check to make sure the VM system provided 0's beyond the true end of
the file mapping (as required by mmap def in 1996 posix 1003.1)
This check was taken from the FreeBSD version of fsx.c.

The result of async io returned in the event.res in addition
to the number of bytes read/written provides negated error
number. The broken libaio defines event.res as unsigned
while the same structure in the kernel defines it as signed.
The kernel indeed treats it as signed, and returns the
negated error number. Till libaio is fixed we provide
the signed long temp var.
Also set errno for each error condition in aio_rw, as the
caller is not aio aware and expects ret(-1)+errno by the
traditional libc convention.

Merge of master-melb:xfs-cmds:28212a by kenmcd.
fsx was calling vfprintf twice without resetting the va_list argument and
this caused a segfault on the second call. Now uses one call to vsnprintf
to print to a buffer and uses that multiple times.

When tracking down an error msg from fsstress, I had no idea what
was going on. So I have added a bunch of comments to the code
and added some more diagnostics (in verbose mode). Have also passed
back some failures which weren't directly before.
Hopefully this will not change the ops which are called for
a given rand-seed run.
