#16610: COMMON: Leak of memory allocated in gzio.cpp

 Run ScummVM configured with `--disable-zlib` and load a save game
 (probably any engine; I tested PhoenixVR and Nancy) which is compressed.

 Attaching ASan reports for sample Nancy and PhoenixVR cases.

 Head of every leaked alloc bt is:
 {{{
 #0 in calloc (scummvm+0xee2cdd) (BuildId:
 9363591178c51873f07dcaf031d3ee64dc39193c)
 #1 in Common::huft_build(unsigned int*, unsigned int, unsigned int,
 unsigned short const*, unsigned short const*, Common::huft**, int*)

 #2 in Common::GzioReadStream::init_dynamic_block()

 #4 in Common::GzioReadStream::readAtOffset(long, unsigned char*, unsigned
 int) common/compression/gzio.cpp:1261:4
 #5 in Common::GzioReadStream::read(void*, unsigned int)
 common/compression/gzio.cpp:1289:21
 }}}

 For now I will reconfigure with `--enable-zlib` and carry on! Ah,
 incidentally, loading nancy3 is significantly faster now, even though I
 was building `--disable-zlib` with `-O3`.
