-** Routines to represent binary data in ASCII and vice-versa
-**
-** This module currently supports the following encodings:
-** uuencode:
-**     	each line encodes 45 bytes (except possibly the last)
-**	First char encodes (binary) length, rest data
-**	each char encodes 6 bits, as follows:
-**	binary: 01234567 abcdefgh ijklmnop
-**	ascii:  012345 67abcd efghij klmnop
-**	ASCII encoding method is "excess-space": 000000 is encoded as ' ', etc.
-**	short binary data is zero-extended (so the bits are always in the
-**	right place), this does *not* reflect in the length.
-** base64:
-**      Line breaks are insignificant, but lines are at most 76 chars
-**      each char encodes 6 bits, in similar order as uucode/hqx. Encoding
-**      is done via a table.
-**      Short binary data is filled (in ASCII) with '='.
-** hqx:
-**	File starts with introductory text, real data starts and ends
-**	with colons.
-**	Data consists of three similar parts: info, datafork, resourcefork.
-**	Each part is protected (at the end) with a 16-bit crc
-**	The binary data is run-length encoded, and then ascii-fied:
-**	binary: 01234567 abcdefgh ijklmnop
-**	ascii:  012345 67abcd efghij klmnop
-**	ASCII encoding is table-driven, see the code.
-**	Short binary data results in the runt ascii-byte being output with
-**	the bits in the right place.
-**
-** While I was reading dozens of programs that encode or decode the formats
-** here (documentation? hihi:-) I have formulated Jansen's Observation:
-**
-**	Programs that encode binary data in ASCII are written in
-**	such a style that they are as unreadable as possible. Devices used
-**	include unnecessary global variables, burying important tables
-**	in unrelated sourcefiles, putting functions in include files,
-**	using seemingly-descriptive variable names for different purposes,
-**	calls to empty subroutines and a host of others.
-**
-** I have attempted to break with this tradition, but I guess that that
-** does make the performance sub-optimal. Oh well, too bad...
-**
-** Jack Jansen, CWI, July 1995.
-**
-** Added support for quoted-printable encoding, based on rfc 1521 et al
-** quoted-printable encoding specifies that non printable characters (anything
-** below 32 and above 126) be encoded as =XX where XX is the hexadecimal value
-** of the character.  It also specifies some other behavior to enable 8bit data
-** in a mail message with little difficulty (maximum line sizes, protecting
-** some cases of whitespace, etc).

-**********************************************************************|
-
- Copyright (C) 1986 Gary S. Brown.  You may use this program, or
- code or tables extracted from it, as desired without restriction.
-
- First, the polynomial itself and its table of feedback terms.  The
- polynomial is
- X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
- Note that we take it "backwards" and put the highest-order term in
- the lowest-order bit.  The X^32 term is "implied"; the LSB is the
- X^31 term, etc.  The X^0 term (usually shown as "+1") results in
- the MSB being 1.
-
- Note that the usual hardware shift register implementation, which
- is what we're using (we're merely optimizing it by doing eight-bit
- chunks at a time) shifts bits into the lowest-order term.  In our
- implementation, that means shifting towards the right.  Why do we
- do it this way?  Because the calculated CRC must be transmitted in
- order from highest-order term to lowest-order term.  UARTs transmit
- characters in order from LSB to MSB.  By storing the CRC this way,
- we hand it to the UART in the order low-byte to high-byte; the UART
- sends each low-bit to hight-bit; and the result is transmission bit
- by bit from highest- to lowest-order term without requiring any bit
- shuffling on our part.  Reception works similarly.
-
- The feedback terms table consists of 256, 32-bit entries.  Notes:
-
-  1. The table can be generated at runtime if desired; code to do so
-     is shown later.  It might not be obvious, but the feedback
-     terms simply represent the results of eight shift/xor opera-
-     tions for all combinations of data and CRC register values.
-
-  2. The CRC accumulation logic is the same for all CRC polynomials,
-     be they sixteen or thirty-two bits wide.  You simply choose the
-     appropriate table.  Alternatively, because the table can be
-     generated at runtime, you can start by generating the table for
-     the polynomial in question and use exactly the same "updcrc",
-     if your application needn't simultaneously handle two CRC
-     polynomials.  (Note, however, that XMODEM is strange.)
-
-  3. For 16-bit CRCs, the table entries need be only 16 bits wide;
-     of course, 32-bit entries work OK if the high 16 bits are zero.
-
-  4. The values must be right-shifted by eight bits by the "updcrc"
-     logic; the shift must be unsigned (bring in zeroes).  On some
-     hardware you could probably optimize the shift in assembler by
-     using byte-swap instructions.
