Microdump writer: stop using new/malloc in compromised context
A recent change in the client-side microdump write (r1404) ended up
introducing a call to new() to instantiate the line buffer that
microdump uses to dump its lines. new/malloc is a luxury we cannot
afford in a compromised context.
This change switches the line buffer to be backed by the dumper
page allocator, which on Linux/Android ends up requesting pages
via mmap.
Also, the microdump write bails out without crashing if the page
allocator failed (crash during severe OOM).
