- Save errno in signal handlers
- Use _exit() in segv handler
Disable immediate auth for delayed-zlib mode
Change port separator to ^ since % is used in ipv6 addresses
Read (and enqueue) packets from interactive input even when
we're waiting for a key exchange.

This should hopefully fix the situation where "~." doesn't work to terminate a
client session when a laptop wakes up. The client will be stuck waiting for a
key exchange on a dead connection, so won't have read the escape character
Add linux/types.h to includes to avoid missing ___u64 etc
Fix building with system libtomcrypt/libtommath
- Fix dbclient with port 0 for server-allocated
- Fix port forwards with a bind address of 127.0.0.1 vs "localhost" etc
