5701f48cf5 Clarify deflateReset() documentation. 
It previously could have been misinterpreted to mean that parameter
changes after deflateInit2() would be reversed, which is not the
case.

0db8fd3714 Fix inflateInit2() bug when windowBits is 16 or 32. 
A windowBits value of 0, 16, or 32 gets the window bits from the
zlib header.  However there is no zlib header for 16, or for 32
when the input is gzip.  This commit sets the window bits for
inflate to 15 if a gzip stream is detected and windowBits was 16
or 32.

72c70060d8 Assure that gzoffset() is correct when appending. 
An open() with O_APPEND followed by an lseek() to determine the
position will return zero for a non-empty file, even though the
next write will start at the end of the file.  This commit works
around that by doing an lseek() to the end when appending.

bddc968b14 Do not force Z_CONST for C++. 
Forcing Z_CONST resulted in an issue when compiling Firefox.  Now
if someone wants to compile zlib as C++ code (which it isn't), now
they will need to #define Z_CONST themselves.

c661c374e8 Do not return Z_BUF_ERROR if deflateParam() has nothing to write. 
If the compressed data was already at a block boundary, then
deflateParam() would report Z_BUF_ERROR, because there was nothing
to write.  With this patch, Z_OK is returned in that case.

03ff48cc67 Remove runtime check in configure for four-byte integer type. 
That didn't work when cross-compiling.  Simply rely on limits.h.
If a compiler does not have limits.h, then zconf.h.in should be
modified to define Z_U4 as an unsiged four-byte integer type in
order for crc32() to be fast.

This also simplifies and makes more portable to check for a four-
byte type using limits.h.
