[PATCH v2 0/2] malloc: split the mtag realloc fix patch

[Szabolcs Nagy]

i decided to split this patch:

 "[PATCH 01/16] malloc: Fix a realloc crash with heap tagging [BZ 27468]"
 https://sourceware.org/pipermail/libc-alpha/2021-March/123226.html

so in the second part i can make more changes, i need review
in that part.

rebased the rest of the patchset on top of this in nsz/mtag.

i'm working on follow up patches where this is useful (because
they touch chunk2mem).

Szabolcs Nagy (2):
  malloc: Fix a realloc crash with heap tagging [BZ 27468]
  malloc: Fix a potential realloc issue with memory tagging
