1.1.1.1
log
@import zlib-1.3.2 (previous was 1.3.1)


Version 1.3.2 has these key updates from 1.3.1:

    Address findings of the 7ASecurity audit of zlib.
	Check for negative lengths in crc32_combine functions.
	Copy only the initialized window contents in inflateCopy.
	Prevent the use of insecure functions without an explicit request.
	Add compressBound_z and deflateBound_z functions for large values.
	Use atomics to build inflate fixed tables once.
	Add --undefined option to ./configure for UBSan checker.
	Copy only the initialized deflate state in deflateCopy.
	Zero inflate state on allocation.
	Add compress_z and uncompress_z functions.
    Complete rewrite of cmake support.
    Remove untgz from contrib.
    Vectorize the CRC-32 calculation on the s390x.
    Remove vstudio projects in lieu of cmake-generated projects.
    Add zipAlreadyThere() to minizip zip.c to help avoid duplicates.
    Add deflateUsed() function to get the used bits in the last byte.
    Fix bug in inflatePrime() for 16-bit ints.
    Add a "G" option to force gzip, disabling transparency in gzread().
    Return all available uncompressed data on error in gzread.c.
    Support non-blocking devices in the gz* routines.
