[RFA 2/3] Improve output of "maintenance info sol-threads" command.

[Joel Brobecker <brobecker@adacore.com>]

This patch does the following:
  - Puts the startfunc and "Sleep func" info on the same line;
  - Renames "Sleep func" into "sleepfunc" to be consistent with
    "startfunc"
  - Avoids the use of a '-' as a separate before the "sleepfunc"
    output, because the '-' looks odd and out of place when the
    "startfunc" field is not printed (ti.ti_startfunc is nul).
  - Use a '=' instead of ':' and avoids the space between
    the name of the value and its value, mostly to help group
    the value with its name.

gdb/ChangeLog:

        * sol-thread.c (info_cb): Rework the output of the "maintenance
        info sol-threads" command a bit.

I could probably commit this one without approval, but someone else's
thoughts would be welcome, since this is a bit cosmetic.
