[svn-r13969] Description:
Initial checkin of API version macro generation script (bin/make_vers), along with configuration file (src/H5vers.txt) and generated header (src/H5version.h). Right now, no version macros are defined, since the main source code and tests need to be adjusted to pay attention to the macros defined. Also, fixed makefile for generating error header files when used with GNU make. Tested on: Mac OS X/32 10.4.10 (amazon) Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
