Rob Norris 9519e7ebcc microzap: set hard upper limit of 1M
The count of chunks in a microzap block is stored as an uint16_t
(mze_chunkid). Each chunk is 64 bytes, and the first is used to store a
header, so there are 32767 usable chunks, which is just under 2M. 1M is
the largest power-2-rounded block size under 2M, so we must set the
limit there.

If it goes higher, the loop in mzap_addent can overflow and fall into
the PANIC case.
