Move the strtab functions from libebl to libdw. Programs often want to
create ELF/DWARF string tables. We don't want (static) linking against
ebl since those are internal functions that might change.
This introduces dwelf_strtab_init, dwelf_strtab_add,
dwelf_strtab_add_len, dwelf_strtab_finalize, dwelf_strent_off,
dwelf_strent_str and dwelf_strtab_free. Documentation for each has
been added to libdwelf.h. The add fucntion got a variant that takes
the length explicitly and finalize was changed to return NULL on
out of memory instead of aborting. All code and tests now uses the
new functions.

asm_begin.c: In function ‘asm_begin’:
asm_begin.c:62:7: error: potential null pointer dereference [-Werror=null-dereference]
__fsetlocking (result->out.file, FSETLOCKING_BYCALLER);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We set result to NULL just before this call in case of error.
Fixed by only calling __fsetlocking when result is not NULL.
strip.c: In function ‘handle_elf.constprop’:
strip.c:1270:31: error: null pointer dereference [-Werror=null-dereference]
elf_assert ((versiondata->d_size / sizeof (Elf32_Word))
~~~~~~~~~~~^~~
src/strip.c:597:37: note: in definition of macro ‘elf_assert’
#define elf_assert(test) do { if (!(test)) goto illformed; } while (0)
^~~~
That is the wrong check, we want to check shndxdata, not versiondata here.
