-- Add spec file for RPM generation for slurm version 14.11.6

-- There were a few minor problems and enhancements that Moe Jette did:

• There were some missing header files includes
• derived_exitcode needs to be printed as %lu rather than %hu.
• the fsize variable was set and never read
• I added some "static" definitions on functions
• Some compilers report warnings for variables definitions NOT at the start of a block (I needed to use xmalloc for the pop_marks variable)
• Some compilers report warnings for the xrealloc return value not used
• In the log functions you are testing for empty strings, so testing if the first character is '\0' is faster than using strlen()
• The xstrfmtcat is faster than using a temporary value and copying data
• slurmdb_association_rec_t was changed to slurmdb_assoc_rec_t
