[RFA] [patch] 'info symbol' to print more info


Greetings,

Currently, 'info symbol' and 'maintenance translate-address' print
just the symbol+offset:

(gdb) maint translate-address 0x2aaaac1f5880
exit+0
(gdb) info symbol 0x2aaaac1f5880
exit in section .text

That's nice, but when I have 100s of shared libraries loaded,
I want to know more.

Attached patch results in:

(gdb) maint translate-address 0x2aaaac1f5880
exit+0 section .text in /usr/lib64/libc.so.6
(gdb) info symbol 0x2aaaac1f5880
exit in section .text of /usr/lib64/libc.so.6

Regtested on x86_64 with no failures.

Ok to commit?

Thanks,
