We have the following undefined symbol error from protocol/server.so:

  glusterfs_mgmt_pmap_signout
  glusterfs_autoscale_threads

See https://review.gluster.org/19225 (bz#1532238)
and https://review.gluster.org/19657 (bz#1550895)

IMO this is a cleaner solution. I.e. moving the above two functions
to libgfrpc (.../rpc/rpc-lib/...)

I would also, for (foolish) consistency sake, like to see
glusterfs_mgmt_pmap_signin() moved from glusterfsd to libgfrpc as
well.

This works on f28/rawhide, with its new, more restrictive run-time
link semantics. The smoke and regression tests on earlier fedora and
centos will confirm that it works on those platforms too.

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

<title>core: run many bricks within one glusterfsd process</title>

This patch adds support for multiple brick translator stacks running
in a single brick server process.  This reduces our per-brick memory usage by
approximately 3x, and our appetite for TCP ports even more.  It also creates
potential to avoid process/thread thrashing, and to improve QoS by scheduling
more carefully across the bricks, but realizing that potential will require
further work.

Multiplexing is controlled by the "cluster.brick-multiplex" global option.  By
default it's off, and bricks are started in separate processes as before.  If
multiplexing is enabled, then *compatible* bricks (mostly those with the same
transport options) will be started in the same process.

<title>build: out-of-tree builds generates files in the wrong directory</title>

And minor cleanup of a few of the Makefile.am files while we're
at it.

Rewrite the make rules to do what xdrgen does. Now we can get rid
of xdrgen.

Note 1. netbsd6's sed doesn't do -i. Why are we still running
smoke tests on netbsd6 and not netbsd7? We barely support netbsd7
as it is.

Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with
libglusterfs? A cut-and-paste mistake? It has no references to
symbols in libglusterfs.

Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_
regex that matches the same lines as the _extended_ regex
"/#(ifndef|define|endif)/". To match the extended regex sed needs to
be run with -r on Linux; with -E on *BSD. However NetBSD's and
FreeBSD's sed helpfully also provide -r for compatibility. Using a
basic regex avoids having to use a kludge in order to run sed with
the correct option on OS X.

Note 4. Not copying the bit of xdrgen that inserts copyright/license
boilerplate. AFAIK it's silly to pretend that machine generated
files like these can be copyrighted or need license boilerplate.
The XDR source files have their own copyright and license; and
their copyrights are bound to be more up to date than old
boilerplate inserted by a script. From what I've seen of other
Open Source projects -- e.g. gcc and its C parser files generated
by yacc and lex -- IIRC they don't bother to add copyright/license
boilerplate to their generated files.

It appears that it's a long-standing feature of make (SysV, BSD,
gnu) for out-of-tree builds to helpfully pretend that the source
files it can find in the VPATH "exist" as if they are in the $cwd.
rpcgen doesn't work well in this situation and generates files
with "bad" #include directives.

E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`,
you get an #include directive in the generated .c file like this:

  ...
  #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h"
  ...

which (obviously) results in compile errors on out-of-tree build
because the (generated) header file doesn't exist at that location.
Compared to `rpcgen ./glusterfs3-xdr.x` where you get:

  ...
  #include "glusterfs3-xdr.h"
  ...

Which is what we need. We have to resort to some Stupid Make Tricks
like the addition of various .PHONY targets to work around the VPATH
"help".

Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/...
looks exactly like -I$(top_srcdir)/rpc/xdr/...  Don't be fooled though.
And don't delete the -I$(top_builddir)/rpc/xdr/... bits

NFS now has the ability to use a separate file for "netgroups" and
"exports". An administrator should have the ability to check the
validity of the files before applying the configuration.

The "glusterfsd" command now has the following additional arguments that
can be used to check the configuration:

   --print-netgroups: Validate the netgroups file and print it out
   --print-exports: Validate the exports file and print it out

<content type='text'>
	Currently there are quite a slew of logs in Gluster that do not
	lend themselves to trivial analysis by various tools that help
	collect	and monitor logs, due to the textual nature of the logs.

	This FEAT is to make this better by giving logs message IDs so
	that the tools do not have to do complex log parsing to break
	it down to problem areas and suggest troubleshooting options.

	With this patch, a new set of logging APIs are introduced that
	take additionally a message ID and an error number, so as to
	print the message ID and the descriptive string for the error.

	New APIs:
		- gf_msg, gf_msg_debug/trace, gf_msg_nomem, gf_msg_callingfn

	These APIs follow the functionality of the previous gf_log*
	counterparts, and hence are 1:1 replacements, with the delta
	that, gf_msg, gf_msg_callingfn take additional parameters as
	specified above.

	Defining the log messages:
	Each invocation of gf_msg/gf_msg_callingfn, should provide an ID
	and an errnum (if available). Towards this, a common message id
	file is provided, which contains defines to various messages and
	their respective strings. As other messages are changed to the
	new infrastructure APIs, it is intended that this file is edited
	to add these messages as well.

	Framework enhanced:
	The logging framework is also enhanced to be able to support
	different logging backends in the future. Hence new configuration
	options for logging framework and logging formats are introduced.

	Backward compatibility:
	Currently the framework supports logging in the traditional
	format, with the inclusion of an error string based on the errnum
	passed in. Hence the shift to these new APIs would retain the log
	file names, locations, and format with the exception of an
	additional error string where applicable.

	Testing done:
	Tested the new APIs with different messages in normal code paths
	Tested with configurations set to gluster logs (syslog pending)
	Tested nomem variants, inducing the message in normal code paths
	Tested ident generation for normal code paths (other paths
		pending)
	Tested with sample gfapi program for gfapi messages
	Test code is stripped from the commit

	Pending work (not to be addressed in this patch (future)):
	- Logging framework should be configurable
	- Logging format should be configurable
	- Once all messages move to the new APIs deprecate/delete older
	  APIs to prevent misuse/abuse using the same
	- Repeated log messages should be suppressed (as a configurable
	  option)
	- Logging framework assumes that only one init is possible, but
	  there is no protection around the same (in existing code)
	- gf_log_fini is not invoked anywhere and does very little
	  cleanup (in existing code)
	- DOxygen comments to message id headers for each message
