797adba286 Change fix for ecl bug in bit-stream-read-bits for improved performance. 
The previous fix in 929d3f9bc9 has worse
performance than not declaring any type on bits, so we now remove the
declaration completely.

929d3f9bc9 Add work-around bit-stream-read-bits for ecl bug in (unsigned-byte 8) negation. 
The compiler in ecl version 10.7.1 generates erroneous code for the negation
of bits in bit-stream-read-bits if bits is declared as an (unsigned-byte 8).
Hence we declare bits as a (signed-byte 8) for ecl, given that ecl does not
generate optimal code in either case, but correct code for the later case.

b18f8fa1da Renamed system from Deflate to deflate to aid symbol naming users. 
Whereas asdf system names are strings and hence case-sensitive, many users
of asdf rely on symbol names being treated specially and down-cased to
system names.  That does not work with "Deflate" but does work with "deflate".
NB that this is a non-compatible change for existing users.

Release 1.0.1
=============
* Renamed Deflate system from Deflate to deflate to support
convenience references to system by symbol rather than string name.
NOTE: This is an incompatible change from all prior releases, all
references to "Deflate" in system definitions will have to be
changed to "deflate" or :deflate or equivalents.
* Preliminary support for ecl has been added: Due to bugs in current
versions of ecl (10.7.1), prior versions of Deflate do not work out
of the box. This version should work better, once fixnum-specialized
arrays work again on 64bit versions of ecl in an upcoming release of
ecl.
