[SHELL] Port to Solaris

- Solaris lacks paths.h and the various _PATH_* #defines.
  Check for them in configure.ac and fall back on the
  usual suspects when they are missing.

- Older Solaris lacks isblank(), and versions that have it
  use a macro.  Check for the declaration in configure.ac
  and fall back on a naive version when missing.

- Older Solaris does not support %jd (intmax_t) in format
  strings, but it does support the PRIdMAX macro from inttypes.h.
  Do a configure check for PRIdMAX and use it in the code.
  If it doesn't exist, define it to "lld" when sizeof(long long)
  equals sizeof(intmax_t) as this is more likely to work on
  older systems.  Otherwise, use "jd" and hope for the best.

- Older Solaris lacks stdint.h, but inttypes.h provides the
  same types and works on all platforms I've tried dash on,
  so just use it instead.

- Older Solaris doesn't like it when vsnprintf() is passed
  a NULL buffer (in violation of the POSIX spec, of course).
  Pass a 1-byte dummy buffer instead.

- Solaris lacks tempfile and mktemp programs.  Fall back on a
  "good-enough" custom function in mkbuiltins.
