Fix a deadlock regarding free_contexts in pxy_compoundv4_execute()

The "if" test introduced a deadlock.  Consider there are 2 items (i.e., x = 2)
in the list of free_contexts, then the following execution order will deadlock:

            T1            T2            T3            T4            T5
            (1)           (2)           (3)           (4)           (5)
          x == 2        x === 1       x == 0        x == 0        x == 0
acquire   x = 1         x = 0         block         block         block

                                        (8)
                                      unblock
                                      x == 2
                                      x = 1 (acquire)

            (6)         (7)            (9)
          x == 0      x == 1          x == 1
          signal      no signal       no signal
release   x = 1       x = 2           x = 2

Thread T4 and T5 will wait forever.

Also, use a separate lock "context_lock", instead of the global "listlock", to
protect the "free_contexts" list.

Updated README file for FSAL_GLUSTER

The README replaces the old config file with the new format.
A sample export file has also been added.
Issue: Ganesha dumps core during a pynfs test (RD2) when started in DEBUG log level.

Fix:
The sequence id is written into a string str, whose size was 31 bytes.The
values of stateid->seqid vary from 1,2 to the largest number possible,
4294967295. The size of the string str has to be 36 bytes long (along with the ':')
to accommodate the largest possible stateid->seqid.
Increasing the string size to fix the issue.
Coverage: Adds option "COVERAGE=ON|OFF" to add "--coverage" flag for gcc

This commits add the "COVERAGE" option to cmake.
If set ON, code will be compiled with "--coverage".
At runtime, ganesha will prouce *.gcda file (if shutdown gently).
Those files can be used as input to gcov or lcov to produce coverage reports.

Don't confuse the BUILDROOT with the final install location

This is a bit tricky.  We must build with the installed files thinking
they are in CMAKE_INSTALL_PREFIX/* but rpmbuild does the install into
a buildroot that is then slurped up into the package as if it is starting
at '/'.  CMAKE_INSTALL_PREFIX is for configure/build time and DESTDIR is
for rpmbuilds %install time.
