[PATCH 0/5] Return error code in get_number

[Yao Qi <yao@codesourcery.com>]

Patch #5 tries to teach GDB to accept convenience variable in MI
commands, in which we use get_number to parse string and get number.
However, get_number returns zero for any kinds of error, and callers
can't tell from it.  Patch #4 changes get_number's interface to
return parsing status and parsed number.  This patch also moves
some printing messages out of get_number, and let the callers to
print messages according to returned status.

Patch #1 - #3 are cleanups and each of them are independent.  This
series is tested on x86_64-linux.
