[svn-r13873] Purpose: Code cleanup
Description:
Changed a macro in H5FDwindows.c from IO_BUF_SIZE to a more specific WINDOWS_MAX_BUF, and moved it to our H5pubconf.h, where users can customize it to their own preference.
This value is needed because of a bug in the Windows _write function, it is unsafe to write buffers larger than 2GB-1 bytes in one write.
Tested:
VS2005 on WinXP.
