Rich DiCroce fa7e69bf30 Allow a limit to be set on the decompressed buffer size for ZlibDecoders (#9924)
Motivation:
It is impossible to know in advance how much memory will be needed to
decompress a stream of bytes that was compressed using the DEFLATE
algorithm. In theory, up to 1032 times the compressed size could be
needed. For untrusted input, an attacker could exploit this to exhaust
the memory pool.

Modifications:
ZlibDecoder and its subclasses now support an optional limit on the size
of the decompressed buffer. By default, if the limit is reached,
decompression stops and a DecompressionException is thrown. Behavior
upon reaching the limit is modifiable by subclasses in case they desire
something else.

Result:
The decompressed buffer can now be limited to a configurable size, thus
mitigating the possibility of memory pool exhaustion.
