getpagesize() will only return positive numbers (there is no negative
page size system) and it can not fail.
Should fix some compiler warnings seen in -portable projects.

write 8 bytes at the time by using a uint64_t pointer. For an
allocation a max of 4 such uint64_t's are written spread over the
allocation. For pages sized and larger, the first page is junked in
such a way.
- Delayed free of a small chunk checks the corresponiding way.
- Pages ending up in the cache are validated upon unmapping or re-use.

around 5 algorithm changes, so any chosen seed is unrepeatable UB.

Prevent an overflow in inet_net_pton(3) when the passed in buffer is2021-01-19T16:43:44+00:00florian2021-01-19T16:43:44+00:00urn:sha1:abe4474fe83b5b1572f8cce65830046c69389bd1
too small in the AF_INET6 case.
Spotted by Brad House (brad AT brad-house.com) with the c-ares
regression test.
The man page says
Caution: The dst field should be zeroed before calling inet_net_pton() as
the function will only fill the number of bytes necessary to encode the
network number in network byte order.
Which seems to suggest that the function should work if the passed in
storage is big enough to hold the prefix, which might be smaller than
sizeof(in6_addr).

Fix two issues related to thread private data in asr.2021-01-06T19:54:17+00:00otto2021-01-06T19:54:17+00:00urn:sha1:a99f91343a365d71d137ae486285fdf049c5cf74
- setting up asr in single thread mode and then starting threads using asr
would lead to multiple threads sharing the same resolver.
- destruction of a thread that has been using asr would leak data.
Problem originally reported by Alexey Sokolov and Uli Schlachter.
