[Bug tapsets/7030] New: signal tapset may be referring to inline functions.

[srikar at linux dot vnet dot ibm dot com]

__group_send_sig_info and specific_send_sig_info seem to be inlined in 2.6.27
kernels. 
__group_send_sig_info and specific_send_sig_info are now just wrapper functions
for send_signal.
Though this issue has been talked in
http://sources.redhat.com/bugzilla/show_bug.cgi?id=1155, we could fix this by
make changes in signal.stp to refer to send_signal rather than
__group_send_sig_info and specific_send_sig_info. 

Currently the failure message when running  sig-by-pid.stp on 2.6.26+ kernel:
stap sig-by-pid.stp 
semantic error: failed to retrieve location attribute for local 'sig'
(dieoffset: 0x4e01ef): identifier '$sig' at

Pass 2: analysis failed.  Try again with more '-v' (verbose) options.

sig-by-pid.stp is a pretty popular script with customers and It got a mention in
a developerworks article.
