This involved using signal() rather than sigaction(), which GNO doesn't have. signal() doesn't have the signal-blocking feature of sigaction(), but I've tried to emulate it.
This code could theoretically break if the ORCA/C varargs implementation changed, but it should be OK in practice.
Also removed some unused code in libbb/xfuncs.printf.c that includes potentially problematic varargs use (defining varargs functions but not necessarily calling va_start/va_end in them).
This disables long argument support, since that requires getopt_long(), which isn't included in GNO. There is a separate library available for it, but it's simpler to avoid depending on that.
This is a BSD-licensed poll() implementation by Brian M. Clapper. Its performance characteristics aren't as good as a "native" poll() would be, but this shouldn't be a problem in practice.
Dmake gets confused if you use over-15-character file names, so they needed to be shortened to get it to work. While I was at it, I also switched _ to . in the filenames so they're fully ProDOS compatible.
The shell/hush_test directory (not needed to build the code) still uses ProDOS-incompatible file names.
GNO doesn't actually implement glob, although it has a header for it. The GNO header is from an old BSD version and is missing some constants we need, so don't use it.
The offset to jitter ratio is now calculated before updating
jitter to make the test more sensitive.

To avoid polling servers frequently slowly increase the interval up
to BIGPOLL when
- no replies are received from a peer
- no source can be selected
- peer claims to be unsynchronized (e.g. we are polling it too
frequently)
When recv() returns with an error, drop code to try to continue
on network errors: I'm not convinced those cases happen in real life.

* on step, poll interval drops to 8.5 mins instead of 32 seconds
* on total loss of all replies (no replies from any peer
for last 8 requests), also drop poll interval to 8.5 mins
instead of 32 seconds
* on send abd recv errors, RETRY_INTERVAL is now 32 seconds,
not 5 seconds
* on timing out listening to reply, instead of unconditional
shortening poll interval by x4, clamp it to NOREPLY_INTERVAL
(512 seconds)
* if a largish offset is seen, clamp nexp poll interval
to 128 seconds, not 64 seconds

Some packages want to install themselves using "-t" to specify
the directory (as supported by GNU coreutils). Add support for the option
for compatibility reasons.

This makes "G" (goto end of input) command work as well as
/search_for_nonexistent_string: both will read to EOF now
even from somewhat slow input (such as kernel's "git log").
