sync_array_object_signalled(): Add a (void) cast to eliminate a gcc warning
about the return value of os_atomic_increment() being ignored.
rw_lock_create_func(): Properly indent the preprocessor directives.
rw_lock_x_lock_low(), rw_lock_x_lock_func_nowait(): Split lines correctly.
rw_lock_set_writer_id_and_recursion_flag(): Silence a Valgrind warning.
Do not mix statements and variable declarations.
To the files touched by the Google patch from c4144 (excluding
include/os0sync.ic because later we removed Google code from that file):
* Remove the Google license
* Remove old Innobase copyright lines
* Add a reference to the Google license and to the GPLv2 license at the top,
as recommended by the lawyers at Oracle Legal.
This patch changes the innodb mutexes and rw_locks implementation.
On supported platforms it uses GCC builtin atomics. These changes
are based on the patch sent by Mark Callaghan of Google under BSD
license. More technical discussion can be found at rb://30

symbols. Use it for all definitions of non-static variables and functions.
lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
