Jilles Tjoelker 523646ee5c sh: Simplify cd-hash interaction.
Instead of rechecking relative paths for all hashed utilities after a cd,
track if any utility in cmdtable depends on a relative path in PATH.
If there is such a utility, cd clears the entire table.

As a result, the '*' in hash no longer happens.

Jilles Tjoelker cdbd40cbb2 sh: Prefer strsignal() to accessing sys_siglist directly.
Accessing sys_siglist directly requires rtld to copy it from libc to the sh
executable's BSS. Also, strsignal() will put in the signal number for
unknown signals (FreeBSD-specific) so we need not do that ourselves.

Unfortunately, there is no function for sys_signame.

Greg Lehey 9aa68a3ffa Add y flag and environment variable LS_SAMESORT to specify the same
sorting order for time and name with the -t option.  IEEE Std 1003.2
(POSIX.2) mandates that the -t option sort in descending order, and
that if two files have the same timestamp, they should be sorted in
ascending order of their names.  The -r flag reverses both of these
sort orders, so they're never the same.  This creates significant
problems for sequentially named files stored on FAT file systems,
where it can be impossible to list them in the order in which they
were created.

Add , (comma) option to print file sizes grouped and separated by
thousands using the non-monetary separator returned by localeconv(3),
typically a comma or period.
