Previous fstab option parsing logic was completely
retarded and did not handle all cases. This fixes the situation
so we now work without any problems.

This commit changes the booster.conf format from a
simple custom format to that of the /etc/fstab.c
See booster_mount(..) for the mount options supported/required
for LD_PRELOADing booster. I'll write a small help doc soon.
This commit also brings in fstab parsing code into libglusterfs
because Darwin libc only supports reading the hardcoded /etc/fstab.

This commit changes the default location of the booster.conf
file from /etc/booster.conf to a directory defined
during the build process.

In brief, when an open is called the VMP-based open is called first.
If that fails, the fallback is the Mount-Point Bypass(MBP) technique
which uses entended attributes to determine if the given
path is a gluster mount. If it is, it goes ahead to create a
glusterfsclient handle. All subsequent calls to this real mount point
get redirected to the glusterfsclient handle. The other fallback is
the actual open syscall on the local file system itself. This happens
when the absence of an extended attribute tells us that the path is
not even a glusterfs mount point.

We define the O_CREAT, etc. flags so that we can remove fcntl.h from the
include path. fcntl.h has certain defines and other lines of
code that redirect application's open and open64 calls to the
syscalls defined by libc.
For us, thats not a Good Thing (TM).

This commit brings into booster the use of VMP based operations
which will allow users of booster to specifiy a VMP and use it
for transparently operating on a glusterfs client context.
Since applications are oblivious to booster's presence, because it is
LD_PRELOAD'ed, we need to specify the VMPs and the corresponding
options like volfile, logfile, loglevel, through a conf file.
By default, this conf file is the /etc/booster.conf. This can be
over-ridden through the GLFS_BOOSTER_CONF environment variable
for the application.
The format of the conf file is very simple for now. Each VMP is
described on a single line with space separated fields.
Format: <Virtual Mount Point> <volfile-path> <log-file> <log-level>
<log-level> takes the string representation of the usual glusterfs
log levels.
