Fix bug 297078 gdbserver signal handling problems caused by diff vki nr/gdb nr and
non reset of "C-ontinued" signal
* To allow vki signame to be used in debuglog:
- pub_core_signals.h : added prototype for Char *VG_(signame)
- m_signals.c : changed static const Char *signame(Int sigNo)
to const Char *VG_(signame)(Int sigNo)
* valgrind-low.c : when the signal to report to gdb has
been reported, clear it so that it is not reported anymore
afterwards.
* m_gdbserver.c: when checking in pass_signals if signal
can be passed without gdb interaction, do a conversion
from vki nr to gdb nr when indexing
(as pass_signals[] is indexed by gdb_nr).
* various gdbserver files:
- used vki_ prefix for some args and variables to clarify
- better debuglog tracing
* modified nlpasssigalrm.vgtest to test SIGCHLD signal
handling followed by a break (to see SIGTRAP is properly
given to gdb).
