The code originates from https://github.com/litespeedtech/ls-hpack
and is explicitly documented as not needing to be initialized.

Glenn Strauss 5ba175269a [core] skip ls-hpack decode work unused by lighttpd 
define LSHPACK_DEC_CALC_HASH 0 to skip work whose results are not used
by lighttpd

Glenn Strauss a25aeaa2f6 [build] remove ls-hpack/deps 
xxHash is provided separately by lighttpd src/algo_xxhash.[ch]

Glenn Strauss 5ec59999dd [build] modify build, includes for xxHash v0.8.0 2020-10-11 12:19:26 -04:00
Glenn Strauss 5a694281da [core] ls-hpack optimizations 
define LSHPACK_DEC_HTTP1X_OUTPUT 0
  lighttpd does not require HTTP/1.1 output compat from HPACK decoder
  ("field-name: value\r\n")

define NDEBUG (in ls-hpack/lshpack.c)
  lighttpd spends upwards of 20% total lighttpd CPU time in HPACK
  encode/decode in h2load test on static file over cleartext (not TLS)
  Defining NDEBUG eliminates some asserts() and results in a small
  but measurable reduction in CPU usage

Glenn Strauss 70b1af0640 [core] link in ls-hpack (EXPERIMENTAL) 
LiteSpeed ls-hpack v2.2.1

XXX: might be better to include this as a git submodule
but minor code changes were made here for portability:
- C99 flexible array members defined as a[] instead of a[0])
- pedantic compiler warnings (excess ';' and missing declarations)
- deletion of large tables from ls-hpack/huff-tables.h (code size)
