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.

innodb_buffer_pool_size >= 4096M on x64 Windows
All three srv_buf_pool related variables are defined as ulong, which is
32-bit on 64-bit Windows. They are changed to 64-bit ulint. Also
system_info.dwPageSize appears to be 32-bit only. Casting to 64-bit
is required.

The memory leak was due to wrong parameters passed into VirtualFree()
call. So, the call fails with Windows error 87. MEM_DECOMMIT can NOT be
used along with MEM_RELEASE. And if the parameter is MEM_RELEASE, the
size parameter must be 0. The function frees the entire region that is
reserved in the initial allocation call to VirtualAlloc.
This issue was introduced by r984.

as type-independent macros instead of functions. Because ut_2pow_round()
and ut_2pow_remainder() no longer assert ut_is_2pow(m), add the assertions
to callers when needed. Also add parentheses to assist the compiler in
common subexpression elimination.
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.
On POSIX, use mmap() and munmap(). On Windows, use VirtualAlloc()
and VirtualFree(). Only on Netware, use ut_malloc_low() and ut_free().
The lower-level functions on POSIX and Windows allow InnoDB to return
memory to the operating system when the buffer pool is shrunk.
