boot: Simplify object erasure
...
This erase_obj() machinery looks like voodoo and creates an awful lot of
noise as soon as we get back to building with -O0. We can do this in a
more simple way by introducing a struct that holds the information we
need on cleanup. When building with optimization enabled, all this gets
inlined and the eraser vanishes.

memory-util: replace memeqzero() by a more generic memeqbyte()
...
The new helper can check for any byte, no just zeroes. The old name is
then converted into a macro that wraps our new version of the helper.

memory-util: add mempmem_safe()
...
This is like memmem_safe() but returns a pointer after the needle,
instead to the beginning of the needle.
This is then used at one place. Not much, but it makes me sleep safer at
night, as it avoids the manual counting done so far.

alloc-util: introduce MALLOC_SIZEOF_SAFE() helper
...
It's a wrapper around malloc_usable_size() that is supposed to be
compatible with _FORTIFY_SOURCES=1, by taking the
__builtin_object_size() data into account, the same way as the
_FORTIFY_SOURCES=1 logic does.
