Support Last-Modified behind proxies which return UTC instead of GMT.

The standard states that GMT must be used, but that UTC is equivalent. Still
parse UTC as otherwise this causes problems for pkg(8). It will refetch
the repository every time 'pkg update' or other remote operations
are used behind these proxies.

RFC2616: "All HTTP date/time stamps MUST be represented in Greenwich Mean
Time (GMT), without exception. For the purposes of HTTP, GMT is exactly equal
to UTC (Coordinated Universal Time).""

r261230 broke the cases where the amount of data to be read is not
known in advance, or where the caller doesn't care and just keeps
reading until it hits EOF.

In fetch_read(): the socket is non-blocking, so read() will return 0
on EOF, and -1 (errno == EAGAIN) when the connection is still open but
there is no data waiting. In the first case, we should immediately
return 0. The EINTR case was also broken, although not in a way that
matters.

In fetch_writev(): use timersub() and timercmp() as in fetch_read().

In http_fillbuf(): set errno to a sensible value when an invalid chunk
header is encountered.

In http_readfn(): as in fetch_read(), a zero return from down the
stack indicates EOF, not an error. Furthermore, when io->error is
EINTR, clear it (but no errno) before returning so the caller can
retry after dealing with the interrupt.

Solve http buffering issues and hangs once and for all (hopefully!) by
simply not trying to return exactly what the caller asked for - just
return whatever we got and let the caller be the judge of whether it
was enough. If an error occurs or the connection times out after we
already received some data, return a short read, under the assumption
that the next call will fail or time out before we read anything.

As it turns out, none of the code that calls fetch_read() assumes an
all-or-nothing result anyway, except for a couple of lines where we
read the CR LF at the end of a hunk in HTTP hunked encoding, so the
changes outside of fetch_read() and http_readfn() are minimal.

While there, replace select(2) with poll(2).
