[gdb/doc] Remove references to no-longer-supported systems
HP-UX and SGI/IRIX are no longer supported. Remove references throughout. AFAICS from the sources, "catch fork" seems to be supported in multiple Unix systems -- just remove the "only works on xxx" remarks. Update the list of supported shared library types. gdb/doc/ChangeLog: * gdb.texinfo (Threads): Remove mention of SGI. (Forks): Remove mention of HP-UX. (Breakpoints): Remove mention of HP-UX. (Set Watchpoints) <hardware watchpoints>: Don't mention HP-UX. Reword in terms of architectures. (Set Catchpoints) <catch exec, catch fork, catch vfork>: Don't mention supported systems. (Convenience Vars): Don't mention HP-UX. (Jumping): Remove mention of HP-UX in comment. (Files) <shared libraries>: Update supported shared library types list. Remove mention of HP-UX. (Native): Remove HP-UX subsection. (SVR4 Process Information): Remove mention of HP-UX.
