[Bug translator/6880] New: more syntax for shared library probing

["fche at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

While the current uprobes syntax can support shared libraries
  probe process("/lib/.....so").... { }
it may be helpful to add some more syntax:

This would resolve the exact library file via heuristics like ldd,
and constrain the uprobes to only named processes.
  probe process("ls").library("libc").function/statement(...) { }

This would search LD_LIBRARY_PATH / /etc/ld.so.conf* for the library
instead of $PATH as for an executable.  Though perhaps we could do
this automatically if the process file name matches "lib*".  Such a
probe could expand to multiple libraries (/lib64 and /lib variants
for example).
  probe library("libc").function/statement(...) { }
