Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously

things reached through a userptr_t).

Create and use async_block() macro; it cuts down on the visual overhead
of blocking on asynchronous operations, when that isn't an important

Gave asynchronous operations approximate POSIX signal semantics. This
will enable us to cascade async operations, which is necessary in order to
properly support DNS. (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).
Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
