Factorises the address code description and printing
of memcheck and helgrind in a common module:
pub_tool_addrinfo.h pub_core_addrinfo.h m_addrinfo.c
At the same time, the factorised code is made usable by other
tools also (and is used by the gdbserver command 'v.info location'
which replaces the helgrind 'describe addr' introduced 1 week ago
and which is now callable by all tools).
The new address description code can describe more addresses
(e.g. for memcheck, if the block is not on the free list anymore,
but is in an arena free list, this will also be described).
Similarly, helgrind address description can now describe more addresses
when --read-var-info=no is given (e.g. global symbols are
described, or addresses on the stack are described as
being on the stack, freed blocks in the arena free list are
See e.g. the change in helgrind/tests/annotate_rwlock.stderr.exp
The patch touches many files, but is basically a lot of improvements
in helgrind output files.
The code changes are mostly refactorisation of existing code.
