66aee54ba4 perf beauty: Add socket level scnprintf that handles ARCH specific SOL_SOCKET
SOL_SOCKET has a different value according to the architecture, some
have it as 0xffff while all the others have it as 1, so a simple string
array isn't usable, add a scnprintf routine that treats it as a special
case, using the array for other values.

795f91db26 perf beauty: Rename socket_ipproto.sh to socket.sh to hold more socket table generators
To avoid having to add new entries to tools/perf/Makefile.perf prep
socket.sh so that it can generate other socket table generators, such as
the upcoming SOL_ socket level one.

c65c83ffe9 perf trace: Allow asking for not suppressing common string prefixes
So far we've been suppressing common stuff such as "MAP_" in the mmap
flags, showing "SHARED" instead of "MAP_SHARED", allow for those
prefixes (and a few suffixes) to be shown:

2e3d7fac9d perf trace: Add a prefix member to the strarray class
So that the user, in an upcoming patch, can select printing it to get
the full string as used in the source code, not one with a common prefix
chopped off so as to make the output more compact.

794f594e0c perf beauty: Switch from GPL v2.0 to LGPL v2.1
The intention is to have this as a library, since it is not perf
specific at all.

I did the switch for the files where I'm the only contributor, with the
exception of a few lines changed by Jiri Olsa.
