add a read-only server variable @@myisam_block_size

Use MYSQL_INSTALL_TARGETS() macro for DLLs 
(libmysql and libmysqld) to ensure that libraries
are signed, if signing is requested.

Remove SIGNCODE_ENABLED variable from create_msi.cmake.in,
it was already removed from other places.

mysql-test/mysql-test-run.pl:
  Don't set --log-error when running embedded server as we don't want the mysqltest output into mysqld.1.err
sql/mysqld.cc:
  Allow one to disable --log-error

- FIND_PROGRAM (signtool) will now get a hint about location of signtool.exe (Windows SDK)
- Targets "package" or "msi" will now fail, l if signing is requested but does not work
  (e.g invalid certificate)
- During install, do not re-sign binaries, if they are already signed.
- Preserve mysqld_error.h timestamp whenever possible. This helps avoiding situations 
where the whole server is rebuilt, whenever comp_err.exe changes (for example after code 
signing, or also after a minor fix in mysys)
- Fix Wix error in UpgradeVersion, if patch part of the version is 0.

Address Monty's review comments

When compiled with SAFEMALLOC or with Windows
Debug CRT, it allocates and initializes 5GB of memory.
The effect is 20 minutes of paging and swapping on
a 4GB VM.

Still allow the test to run with optimized binaries.
Memory is not initialized in this case,  malloc() 
of 5GB  size will not bring the whole buffer into 
physical memory.
