trumptr: some comments.
crunchcc: use my hacked objcopy to support interposition on allocation functions which are static, address-taken and/or called from the defining module.
dumpallocs: fix bug where sizeofs that are cast (e.g. to int) were being wrongly ignored.
Makefile in test/ now supports simple automatic checking.
crunchcc: tolerate empty LIBCRUNCH_ALLOC_FNS.
Demote stubs.c to an example, now that stub generation happens automatically.

--HG--
rename : src/stubs.c => src/stubs.c.example
Support LIBCRUNCH_LAZY_HEAP_TYPES variable for signalling sizealike data types used in malloc().
Iterate over uniqtypes using ELF symtab directly, instead of slower dladdr() approach.
Scan for lazy types in program objects as well as -types.so objects.
Add lazy typing test case.
