<title>libglusterfs: Move devel headers under glusterfs directory</title>

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation &lt;&gt; in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...

Only compile-tested!

<title>core: use syscall wrappers instead of direct syscalls - miscellaneous</title>

various xlators and other components are invoking system calls
directly instead of using the libglusterfs/syscall.[ch] wrappers.

If not using the system call wrappers there should be a comment
in the source explaining why the wrapper isn't used.

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

* When a writev call occurs, the client compresses the data before
  sending it to server. On the server, compressed data is decompressed.
  Similarly, when a readv call occurs, the server compresses the data
  before sending it to client. On the client, the compressed data is
  decompressed. Thus the amount of data sent over the wire is minimized.

* Compression/Decompression is done using Zlib library.

* During normal operation, this is the format of data sent over wire :
  &lt;compressed-data&gt; + trailer(8)
  The trailer contains the CRC32 checksum and length of original
  uncompressed data. This is used for validation.

HOW TO USE
----------
Turning on compression xlator:
gluster volume set &lt;vol_name&gt; compress on

Configurable options:
gluster volume set &lt;vol_name&gt; compress.compression-level 8
gluster volume set &lt;vol_name&gt; compress.min-size 50
