Add Signal Tracing to strace (easy)

[bonefish]

ATM strace prints the traced syscalls only. It could (optionally) also trace signals.

[absabs]

when applied the patch, strace now can trace signals tested as following:

1. in one terminal

strace sleep 666

2. in another terminal

kill -s sig pid where sig is the signal such as URG\USR1 and so on.

oh, some code for debug was not removed. Now the newpatch should fix the bug Replying to absabs:

sorry for my mistake. Give up "patch\newpatch\newpatch.2", we need only the final.patch Replying to absabs:

Thanks for your patch! It looks very nice! Do you have the time to fix the coding style problems (constants have the 'k' prefix, so it would be kSignalName), and add an option to make signal tracing optional? If not, I can make the changes, too, just tell.

No problem. I will upload the patch later. :) Replying to axeld:

Thanks! Applied in hrev23436 with minor changes (-g now turns off signal tracing, it's enabled by default).
