Yuval Brik 80169b1f0a zlib: decompression throw on truncated input
Check for unexpected end-of-file error when decompressing. If the output
buffer still has space after decompressing and deflate returned Z_OK or
Z_BUF_ERROR - that means unexpected end-of-file. Added
test-zlib-truncated.js for the case of truncated input. Fixed the zlib
dictionary test to not end the inflate stream on a truncated output (no
crc) of deflate
