disable partition processing if we open frm file only

1. added check to fill_schema_schemata() func.
   if we have db lookup value we should check that db exists
2. added check to get_all_tables() func
   if we have lookup db name or tables name values we shoud check that
   these values are not empty strings
3. fixed typo

which is faster than open_table_def() func.
This patch fixes the porblem with information_schema test timeout.

    Fix a typing error in a conditional compiling directive
    (reported by Vasil Dimov: Thanks !),
    and improve their nesting ("MAIN" independent of platform).

Completion patch, since it is possible that Log_event::write_header()
is called with no current thread.

When starting the server, there is no thread available, but
MYSQL_BIN_LOG::open() is called to initialize the binary log. The
function writes a format description log event to the binary log,
which means that Log_event::write_header() can be called with no
current thread object available.

  Additional changes for bug#29903
  - Changed to do embedded build part as normal build, when
    WITH_EMBEDDED_SERVER is set.
  - Allow both normal and debug build with embedded.
  - Build static embedded library by pointing out all source and compile
    it all, i.e. not building libraries from libraries, not portable.
  - Let embedded use generated files from the "sql" directory, added
    dependencies to make sure built before embedded.
  - Mark library "dbug" in TARGET_LINK_LIBRARIES() with "debug", so only
    linked in when debug target is used.
  - Removed change of target name with "mysqld${MYSQLD_EXE_SUFFIX}", as
    others can't depend on it, not defined at configure time. Instead
    set the output file name.
  - Created work around for bug in CMake 2.4.6 and output names, to
    set the "mysqld<suffix>.pdb" name to the same base name.
  - Set the correct manifest "name" (patch by iggy)
