ut_list_mutex would be used uninitialized when innodb_use_sys_malloc=1.
This fix addresses Issue #181.
ut_mem_block_list_init(): Rename to ut_mem_init() and make public.
ut_malloc_low(), ut_free_all_mem(): Add ut_a(ut_mem_block_list_inited).
mem_init(): Call ut_mem_init().
Unprotected updates to ut_total_allocated_memory in
os_mem_alloc_large() and os_mem_free_large(), called during
fast index creation, may corrupt the variable and cause assertion failures.
Also, add UNIV_MEM_ALLOC() and UNIV_MEM_FREE() instrumentation around
os_mem_alloc_large() and os_mem_free_large(), so that Valgrind can
detect more errors.

malloc(), realloc(), free() when innodb_use_sys_malloc is set.
ut_free_all_mem(): If innodb_use_sys_malloc is set, do nothing,
because then ut_mem_block_list_inited will never be set.
log_init(): Use mem_alloc() instead of ut_malloc(), so that the
memory will be freed. (Tested with Valgrind, although it is not
clear why the memory would be freed.)

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.
Add innodb_locks.lock_data column and some relevant tests.
For record locks this column represents the ordering fields of the
locked row in a human readable, SQL-valid, format.

functions.
ut_malloc_low(): Flag the block with UNIV_MEM_ALLOC(). Do not flag the
block with UNIV_MEM_FREE() in ut_free(), because it would cause bogus
Valgrind warnings in the underlying memory allocator.
mem_pool_create(): Flag the data area with UNIV_MEM_FREE().
mem_pool_fill_free_list(): Flag the area header with UNIV_MEM_ALLOC().
mem_area_alloc(): Flag the data area with UNIV_MEM_ALLOC().
mem_area_free(): Flag the data area with UNIV_MEM_FREE().
mem_heap_alloc(): Flag the buffer with UNIV_MEM_ALLOC().
mem_heap_block_free(): Flag the block with UNIV_MEM_FREE().
mem_heap_free_top(): Flag the block with UNIV_MEM_FREE().
