Bug #47095: Can't open_files_limit really be larger than 65535?

Browse Source 
Several problems addressed:

1. The maximum value for --open_files_limit on non-windows boxes
is now raised to UINT_MAX (the maximum possible without significant
changes in the code). The maximum value on windows is kept to be
2048 due to a known limitation (bug 24509).

2. mysqld_safe now supports --open_files_limit=xx in addition to 
--open-files-limit=xx

3. mysqld_safe always passes through --open[_-]files[_-]limit
to the underlying mysqld. It used to pass it through only if it 
the user running the script has access to the root directory or
there was an --user argument specified.

4. Fixed a prototype in my_file.c to match its counterpart in 
the other #ifdef branch.
