[RFA/testsuite] Increase expect buffer size (related to GPLv3)

[Joel Brobecker <brobecker at adacore dot com>]

Hello,

After switching "info copying/warranty" to GPLv3, the testsuite showed
one regression (expected), and two ERRORs because of expect buffer
overflow. The overflow comes from the fact that the GPLv3 terms are
much longer than the terms in GPLv2.

I think the attached patch is the appropriate change, but perhaps
there is a way to change the buffer size locally for the test or
the testcase, instead of expanding it globally for all testcases.
I really don't think that growing the buffer to 30kb (from 20kb)
is a big deal, but perhaps it has some effects that I haven't noticed
(like performance hits)... Hence the RFA rather than committing it
using the obvious rule.

        * lib/gdb.exp (default_gdb_init): Increase expect buffer size
        to 30000 (from 20000).

Tested on x86-linux. No regression.
OK to apply?

Thanks,
