mksh R40 Release Candidate 1

Browse Source 
Testsuite:
• add new need-pass: {yes|no} attribute, default yes
• exit with 1 if a need-pass test failed unexpectedly
  idea by Kacper Kornet <draenog@pld-linux.org>
• mark utf8bom-2 as need-pass: no
Infrstructure:
• add housekeeping function for making a tty raw
• switch functions with unused results to void
• struct op: u.charflag contains last char of ;; in TPAT
• var.c:arraysearch is now a global function
Language:
• add ;& (fall through) and ;| (examine next) delimiters
  in addition to ;; (end case) as zsh extensions, because
  POSIX standardised on ;& already
• add -A (read into array), -N (read exactly n bytes),
  -n (read up to n bytes), -t (timeout) flags for read
  from ksh93
• allow read -N -1 or -n -1 to slurp the entire input
• add -a (read into array the input characters) extension
  specific to mksh to read, idea by David Korn
• add -e (exit with error if PWD was not set correctly
  after a physical cd) to cd builtin, mandated by next
  POSIX, and change error codes accordingly
Rewrites:
• full rewrite of read builtin and its manpage section
• add regression tetss for most of the new functionality
• duplicate hexdump demo tests for use of read -a
• use read -raN-1 in dot.mkshrc to get NUL safe base64,
  DJB cdb hash and Jenkins one-at-a-time hash functions
