Mark Wielaard 461cc5c003 Cleanup GPL header address notices by using http://www.gnu.org/licenses/ 
Sync VEX/LICENSE.GPL with top-level COPYING file. We used 3 different
addresses for writing to the FSF to receive a copy of the GPL. Replace
all different variants with an URL <http://www.gnu.org/licenses/>.

The following files might still have some slightly different (L)GPL
copyright notice because they were derived from other programs:

- files under coregrind/m_demangle which come from libiberty:
  cplus-dem.c, d-demangle.c, demangle.h, rust-demangle.c,
  safe-ctype.c and safe-ctype.h
- coregrind/m_demangle/dyn-string.[hc] derived from GCC.
- coregrind/m_demangle/ansidecl.h derived from glibc.
- VEX files for FMA detived from glibc:
  host_generic_maddf.h and host_generic_maddf.c
- files under coregrin/m_debuginfo derived from LZO:
  lzoconf.h, lzodefs.h, minilzo-inl.c and minilzo.h
- files under coregrind/m_gdbserver detived from GDB:
  gdb/signals.h, inferiors.c, regcache.c, regcache.h,
  regdef.h, remote-utils.c, server.c, server.h, signals.c,
  target.c, target.h and utils.c

Plus the following test files:

- none/tests/ppc32/testVMX.c derived from testVMX.
- ppc tests derived from QEMU: jm-insns.c, ppc64_helpers.h
  and test_isa_3_0.c
- tests derived from bzip2 (with embedded GPL text in code):
  hackedbz2.c, origin5-bz2.c, varinfo6.c
- tests detived from glibc: str_tester.c, pth_atfork1.c
- test detived from GCC libgomp: tc17_sembar.c
- performance tests derived from bzip2 or tinycc (with embedded GPL
  text in code): bz2.c, test_input_for_tinycc.c and tinycc.c

README.txt 

On 4 Apr 06, the debuginfo reader (m_debuginfo) was majorly cleaned up
and restructured.  It has been a bit of a tangle for a while.  On 18 Sep 14
the STABS support was completely removed. The new structure looks like this:

                  debuginfo.c 
  
                   readelf.c

                  readdwarf.c

                   storage.c

Each .c can only call those below it on the page.

storage.c contains the SegInfo structure and stuff for 
maintaining/searching arrays of symbols, line-numbers, and Dwarf CF 
info records.

readdwarf.c parses the relevant kind of info and call storage.c to
store the results.

readelf.c reads ELF format, hands syms directly to storage.c,
then delegates to readdwarf.c for debug info.  All straightforward.

debuginfo.c is the top-level file, and is quite small.

There are 2 goals to this:

(1) Generally tidy up something which needs tidying up

(2) Introduce more modularity, so as to make it easier to add
    readers for other formats, if needed

Rationale for (1) and (2) are obvious.

Originally there was also goal (3) Simplify the stabs reader.
But stabs support was broken since 3.9.0 and completely removed in 3.10.0.

The worst thing is that it is the stabs type reader that was crashing,
not the stabs line-number reader.
Old versions of the stabs type reader can be found in the subversion repository
as m_debuginfo/UNUSED_STABS.txt, the stabs line-number reader was in
m_debuginfo/readstabs.c. The old version of this file explained more
about the setup.
