Commit 1d37186fe2 (ash: add bash-compatible EPOCH variables) added
support for the EPOCHSECONDS and EPOCHREALTIME variables.
These variables are dynamic and therefore require the VDYNAMIC flag
to be non-zero. However, this is only the case if support for the
RANDOM variable is enabled.
Give VDYNAMIC a non-zero value if either EPOCH variables or RANDOM
are enabled.

Commit 8baa643a3 (lineedit: match local directories when searching
PATH) included subdirectories of the current directory in the search
when tab-completing commands.
Unfortunately a short time later commit 1d180cd74 (lineedit: use
strncmp instead of is_prefixed_with (we know the length)) broke
this feature by returning an incorrect length for the array of paths.
Fix the length and reinstate matching of subdirectories.

of a <plus-sign> to punctuate the end of the primary expression
need not be supported, and find shall request affirmation of the

the response on standard input is affirmative, the utility shall be

Found one case where SIGHUP does need some handling.
ash does not restore tty pgrp when killed by SIGHUP, and
this means process which started ash needs to restore it,
or it would get backgrounded when trying to use tty.

The 32-bit integer part of the NTP timestamp overflows in year 2036,
which starts the second NTP era.
Modify the timestamp conversion to shift values between 1900-1970 (in
the first era) to the second era to enable the client to measure its
offset correctly until year 2106 (assuming 64-bit time_t).
Also update the conversion from double used when stepping the clock to
work with 64-bit time_t after reaching the maximum 32-bit value in 2038
and the server conversion to work correctly in the next NTP era.

The memcpy invocations in the subCommand function, modified by this
commit, previously used memcpy with overlapping memory regions. This is
undefined behavior. On Alpine Linux, it causes BusyBox ed to crash since
we compile BusyBox with -D_FORTIFY_SOURCE=2 and our fortify-headers
implementation catches this source of undefined behavior [0]. The issue
can only be triggered if the replacement string is the same size or
shorter than the old string.
Looking at the code, it seems to me that a memmove(3) is what was
actually intended here, this commit modifies the code accordingly.
