`--help` is a perfectly valid parameter and both `mysqladmin` and
`mysql_waitpid` should exit with success (zero errror code).

Fix test whether process is alive in mysqltest.
Also fix SHUT_RD definition on Windows to be SD_RECEIVE.
SD_BOTH was used instead prior to this patch, and this would
occasionally make mysql_shutdown() fail - when the socket for the current connection
is not able send the COM_SHUTDOWN response anymore.
DESCRIPTION
===========
Buffer overflow is reported in a lot of code sections
spanning across server, client programs, Regex libraries
etc. If not handled appropriately, they can cause abnormal
behaviour.
ANALYSIS
========
The reported casea are the ones which are likely to result
in SEGFAULT, MEMORY LEAK etc.
FIX
===
- sprintf() has been replaced by my_snprintf() to avoid
buffer overflow.
- my_free() is done after checking if the pointer isn't
NULL already and setting it to NULL thereafter at few
places.
- Buffer is ensured to be large enough to hold the data.
- 'unsigned int' (aka 'uint') is replaced with 'size_t'
to avoid wraparound.
- Memory is freed (if not done so) after its alloced and
used.
- Inserted assert() for size check in InnoDb memcached
code (from 5.6 onwards)
- Other minor changes
(cherry picked from commit 3487e20959c940cbd24429afa795ebfc8a01e94f)
An addition to original patch:
- use FN_REFLEN instead of HOST_NAME_MAX (the latter can be undefined)
- avoid calling gethostname() on every prompt construction by caching it
Introduce `\H` option which behaves mostly like `\h`. The only exception is
when the client connects to the server hosted on localhost. In this case, the
hostname will be used instead.
- Removed some QQ markers
- Removed some rows not compatible with valgrind 3.9.0
- Made mysql_install_db.sh more silent by default. --verbose now gives more information
- Added assert that auto-increment doesn't generate 0 (safety)
- Removed thd->set_time() in some places as it's set in init_for_queries()
- Fixed some --big tests in tokudb
- Fixed a bug in mysql_client_test.cc where sql_mode was not properly reset
mysql.cc:
Unlike the main MYSQL structure, kill_mysql did not have MYSQL_OPT_PROTOCOL set.
Move all connection-related settings to a separate function and
use it both for the main MYSQL and for kill_mysql.
cherry-pick f1daf9ce from 10.0 branch
-------------------------------------
Fix build failures caused by new C runtime library
- isnan, snprintf, struct timespec are now defined, attempt to
redefine them leads
- P_tmpdir, tzname are no more defined
- lfind() and lsearch() in lf_hash.c had to be renamed, declaration
conflicts with some C runtime functions with the same name declared in
a header included by stdlib.h
Also fix couple of annoying warnings :
- remove #define NOMINMAX from config.h to avoid "redefined" compiler
warnings(NOMINMAX is already in compile flags)
- disable incremental linker in Debug as well (feature not used much
and compiler crashes often)
Also simplify package building with Wix, require Wix 3.9 or later
(VS2015 is not compatible with old Wix 3.5/3.6)
Fix test whether process is alive in mysqltest.
Also fix SHUT_RD definition on Windows to be SD_RECEIVE.
SD_BOTH was used instead prior to this patch, and this would
occasionally make mysql_shutdown() fail - when the socket for the current connection
is not able send the COM_SHUTDOWN response anymore.
10.0 has an "analyze table .. persistent for all" syntax. This adds
--persistent to mysqlcheck(mysqlanalyize) to perform this extended
analyze table option.
