The function p9dialparse() returns the host as a sockaddr_storage
structure instead of a u32int, to be able to handle both IPv4
and IPv6 addresses. Because the sockaddr_storage structure also
handle port numbers and Unix path names, there is no longer
need to set them in the calling functions. However, these values
are still returned for convenience.
The sockaddr_in and sockaddr_un structures have been replaced
by sockaddr_storage to handle Unix, IPv4 and IPv6 sockets.
Names and addresses are resolved using either gethostbyname()
or getaddrinfo() functions.
The getaddrinfo() function is documented in RFC2553 and standardized
since POSIX.1-2001. It supports both IPv4 and IPv6 addresses.
The gethostbyname() function is deprecated since POSIX.1-2008.
However, some libc implementations don't handle getaddrinfo()
properly, thus we preferred to try gethostbyname() first.
I've tried to preserve most of the old code logic to prevent
from surprising or unwanted behavior.

These functions are equivalent to vtSha1 and vtSha1Check
from the old libventi and are particularly used by Fossil.

Otherwise, the type of the expression will be int, and if written to
a uvlong (or just a ulong on most 64-bit systems), it will be
sign-extended.
This was going on in drawfcall with Mouse.msec, which is declared
as a ulong.
This fix assumes that the protocols only send unsigned numbers,
which is true.
distinguish between "cannot receive without blocking"
and "EOF on connection".
In libmux, do not elect async guys muxers, so that
synchronous RPC calls run in the main event loop
(e.g., in eresized) do not get stuck.
Fixes problem reported by Lu Xuxiao, namely that
jpg etc. would spin at 100% cpu usage.
