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

Problem:
The iattbuf ptr stored in arbiter's inode context was not freed during inode
forget.
Fix:
Change it to a statically allocated value so that we don't have to deal
with allocating/freeing it.

Problem: The throughput for a 'dd' workload was much less for arbiter
configuration when compared to normal replica-3 volume. There were 2
issues:
i)arbiter_writev was using the request dict as response dict while
unwinding, leading to incorect GLUSTERFS_WRITE_IS_APPEND and
GLUSTERFS_OPEN_FD_COUNT values (=4), leading to immediate post-ops
because is_afr_delayed_changelog_post_op_needed() failed due to
afr_are_multiple_fds_opened() check.
ii) The arbiter code in afr was setting local->transaction.{start and len} =0
to take full file locks. What this meant was even for simultaenous but
non-overlapping writevs, afr_transaction_eager_lock_init() was not
happening because afr_locals_overlap() always stays true. Consequently
is_afr_delayed_changelog_post_op_needed() failed due to
local->delayed_post_op not being set.
Fix:
i) Send appropriate response dict values in arbiter_writev.
ii) Modify flock params instead of local->transaction.{start and len} to
take full file locks in the transaction.
Also changed _fill_writev_xdata() in posix to fill rsp_xdata for
whatever key is requested for.

Revisiting http://review.gluster.org/#/c/11814/, which unintentionally
introduced warnings from libtool about the xlator .so names.
According to [1], the -module option must appear in the Makefile.am
file(s); if -module is defined in a macro, e.g. in configure(.ac),
then libtool will not recognize that this is a module and will emit a
warning.

We've been lucky that we haven't had any symbol collisions until now.
Now we have a collision between the snapview-client's svc_lookup() and
libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi.
As a short term solution all the snapview-client's FOP methods were
changed to static scope. See http://review.gluster.org/11805. This
works in snapview-client because all the FOP methods are defined in
a single source file. This solution doesn't work for other xlators
with FOP methods defined in multiple source files.
To address this we link with libtool's '-export-symbols $symbol-file'
(a wrapper around `ld --version-script ...` --- on linux anyway) and
only export the minimum required symbols from the xlator sharedlib.
N.B. the libtool man page says that the symbol file should be named
foo.sym, thus the rename of *.exports to *.sym. While foo.exports
worked, we will follow the documentation.

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.

While building, the following warning is displayed:
xlators/features/arbiter/src/Makefile.am:7: variable `_la_LIBADD' is defined but no program or
xlators/features/arbiter/src/Makefile.am:7: library has `_la' as canonical name (possible typo)
The _la_LIBADD really seems like a typo, dropping it should not be harmful to
anything, except for the warning that will now be gone.

This patch adds the arbiter translator into the tree. This is a server
side xlator used for replica 3 volumes. It sits above posix and will be
loaded on the 3rd (last) brick of every afr subvolume in a replica 3
configuration. It intercepts inode read/write operations: reads are
unwound with ENOTCONN, inode writes are unwound with success without
actually passing them down to posix. Metadata operations are allowed to
pass through.
The CLI for creating a 3 way replica with arbiter is also added but kept
disabled (A 'normal' 3 way replica is created instead).
This patch is a part of the arbiter logic implementation for 3 way AFR,
details of which can be found at http://review.gluster.org/#/c/9656/
