zlib: fix gzip member head/buffer boundary issue

Make sure that, even if an `inflate()` call only sees the first
few bytes of a following gzip member, all members are decompressed
and part of the full output.

This change also modifies behaviour for trailing garbage:
If there is trailing garbage which happens to start with the
gzip magic bytes, it is no longer discarded but rather throws
an error, since we cannot reliably tell random garbage from
a valid gzip member anyway and have to try and decompress it.
(Null byte padding is not affected, since it has been pointed
out at various occasions that such padding is normal and
discarded by `gzip(1)`, too.)

Adds tests for the special case that the first `inflate()` call
receives only the first few bytes of a second gzip member but
not the whole header (or even just the magic bytes).

zlib: add support for concatenated members

According to the spec gzipped archives can contain more than one
compressed member. Previously Node's gzip implementation would only
unzip the first member and throw away the rest of the compressed data.
Issue #4306 is an example of this occurring in daily use.
