ee474ff2d1 Fix pending buffer overflow assert with LIT_MEM allocation. 
Since each element in s->d_buf is 2 bytes, the sx index should be
multiplied by 2 in the assert.

Fixes #897

4bd9a71f35 Remove fdopen #defines in zutil.h.

15c45adb76 Fix decision on the emission of Zip64 end records in minizip. 
The appnote says that if the number of entries in the end record
is 0xffff, then the actual number of entries will be found in the
Zip64 end record. Therefore if the number of entries is equal to
0xffff, it can't be in the end record by itself, since that is an
instruction to get the number from the Zip64 end record. This code
would just store 0xffff in the end record in that case, not making
a Zip64 end record. This commit fixes that.

ac8f12c97d Add LIT_MEM define to use more memory for a small deflate speedup. 
A bug fix in zlib 1.2.12 resulted in a slight slowdown (1-2%) of
deflate. This commit provides the option to #define LIT_MEM, which
uses more memory to reverse most of that slowdown. The memory for
the pending buffer and symbol buffers is increased by 25%, which
increases the total memory usage with the default parameters by
about 6%.

73331a6a04 Reject overflows of zip header fields in minizip. 
This checks the lengths of the file name, extra field, and comment
that would be put in the zip headers, and rejects them if they are
too long. They are each limited to 65535 bytes in length by the zip
format. This also avoids possible buffer overflows if the provided
fields are too long.
