Document support for 'info proc' on FreeBSD.
Since the 'info proc' support on FreeBSD does not use /proc, reword
the documentation for 'info proc' to not assume /proc. This includes
renaming the node to 'Process Information' and suggesting that
additional process information can be queried via different
OS-specific interfaces. This is also cleans up the description of
'info proc' support for core files a bit as /proc is not used for core
file support on any current platform.
gdb/ChangeLog:
* NEWS: Document that 'info proc' now works on FreeBSD.
gdb/doc/ChangeLog:
* gdb.texinfo (pwd): Update cross-reference for Process Information
node and remove explicit /proc reference.
(Native): Rename subsection from SVR4 Process Information to
Process Information.
(Process Information): Reword introduction to be less /proc
centric. Document support for "info proc" on FreeBSD.
