ea096d6c13 ntpd: decrease MIN_FREQHOLD by 2, increase "penalty" for largish offset x2
> 2018-07-25:
> ntpd: increase MIN_FREQHOLD by 3
> This means we'll start correcting frequency ~5 minutes after start,
> not ~3.5 ones.
> With previous settings I still often see largish ~0.7s initial offsets
> only about 1/2 corrected before frequency correction kicks in,
> resulting in ~200ppm "correction" which is then slowly undone.

Review of real-world results of the above shows that with small
initial offsets, freq correction can be allowed to kick in sooner,
whereas with large (~0.8s) offsets, we still start freq correction
a bit too soon.

Let's rebalance this a bit.

6b4960155e nslookup: implement support for SRV records
Add support for querying and parsing SRV DNS records.

8c3b520d4f nslookup: handle replies without RRs
Under some circumstances, a DNS reply might contain no resource records,
e.g. when a valid domain is queried that does not have records of the
requested type.

Example with nslookup from BIND dnsutils:

    $ nslookup -q=SRV example.org
    Server:	10.11.12.13
    Address:	10.11.12.13#53

    Non-authoritative answer:
    *** Can't find example.org: No answer

Currently the busybox nslookup applet simply prints nothing after the
"Non-authoritative answer:" line in the same situation.

This change modifies nslookup to either print "Parse error" or "No answer"
diagnostics, depending on the parse_reply() return value.

ed79af77a4 config: PID_FILE_PATH required for FEATURE_CROND_SPECIAL_TIMES
When crond is built with FEATURE_CROND_SPECIAL_TIMES enabled, it creates
a file called 'crond.reboot' at CONFIG_PID_FILE_PATH, but if
FEATURE_PIDFILE is disabled, this will be an empty string and the file
will be created in the root directory, which is undesirable.

This commit makes PID_FILE_PATH depend on FEATURE_CROND_SPECIAL_TIMES as
well as FEATURE_PIDFILE so that you get sensible behaviour in crond when
FEATURE_PIDFILE is switched off.

ad27d44ebe runsv: Use 64 prefix syscall if we have to
Some 32-bit architectures no longer have the 32-bit time_t syscalls.
Instead they have suffixed syscalls that returns a 64-bit time_t. If
the architecture doesn't have the non-suffixed syscall and is using a
64-bit time_t let's use the suffixed syscall instead.

This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel
headers.

If an architecture only supports the suffixed syscalls, but is still
using a 32-bit time_t report a compilation error. This avoids us have to
deal with converting between 64-bit and 32-bit values. There are
currently no architectures where this is the case.

headers.

If an architecture only supports the suffixed syscalls, but is still
using a 32-bit time_t report a compilation error. This avoids us have to
deal with converting between 64-bit and 32-bit values. There are
currently no architectures where this is the case.

b7b7452f29 date: Use 64 prefix syscall if we have to
Some 32-bit architectures no longer have the 32-bit time_t syscalls.
Instead they have suffixed syscalls that returns a 64-bit time_t. If
the architecture doesn't have the non-suffixed syscall and is using a
64-bit time_t let's use the suffixed syscall instead.

This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel
headers.

If an architecture only supports the suffixed syscalls, but is still
using a 32-bit time_t fall back to the libc call.

Converted a few 16-bit variables and small arrays to 32-bit.

Stopped pulling desc->FOO members into temporary local variables
in gen_bitlen(): on register-starved arches, this is a loss,
temporaries go into stack slots.

Sprinkled a few "const" on pointer arguments.
