api: versioned symbols in libgfapi.so for compatibility
Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0
Revisited to address broken build on Mac OS X
See http://review.gluster.org/9036
Rebased to include http://review.gluster.org/#/c/9376/ (glfs_resolve())
but note that gerrit's "Rebase Change" couldn't do it.
N.B. noticed that glfs_get_volumeid() decl in glfs.h was missing
the __THROW, added it.
On systems using ELF and the GNU toolchain, symbol versions are created
with a .symver asm operand in the .c source file. Clang is claimed to
be compatible with gcc, so we'll pretend for now that this also works
with clang.
On Mac OS X, aliases are created with __asm "magic" in the .h header
file. In the normal case, when both the decl and defn match, that's
all that's needed. In our case though the decl and defn don't match ---
we have, e.g. a defn such as 'int glfs_foo(...)' and the corresponding
decl is 'int pub_glfs_foo(...)'. To make this work we create the necessary
aliases in the library at link time with the -alias_list link option.
Note that this results in there being pairs of symbols in the .dylib,
e.g. _pub_glfs_foo and _glfs_foo$GFAPI_3.4.0. We could use another
link option, -unexported_symbols_list to elide the _pub_glfs_* symbols.
(And we probably should.)
Linux symbol versioning was essentially copied from Solaris; in general
I would expect this to "just work" on Solaris, but until someone tries
we don't really know.
