feature required: support PCRE2

[stdanley]

Because of the api change, this module can't work with PCRE2 ,which nginx has already handled correctly, using macro NGX_PCRE2.
the problem is when nginx chooses PCRE2, configuration phase fails because the configuration script of this module relies on pcre_version , that function had been removed from pcre2, replaced with pcre2_config.
openresty has plan to support pcre2 in lua module officially?

Cool, this is a work in progress

PCRE2 support has been merged, but pcre_version is still required by config script ("force pcre_version symbol to be required when PCRE is statically linked")

PR is welcomed. @piotrp

I will close this issue since PCRE2 is supported.
You can create another issue. @piotrp

Lines 407 to 409 in cafa6f5

	if [ $USE_PCRE = YES -o $PCRE != NONE ] && [ $PCRE != NO -a $PCRE != YES ] && [ $PCRE2 != YES ]; then
	# force pcre_version symbol to be required when PCRE is statically linked

this is conditionally required, so it's as expected, no ?

[piotrp]

This condition is also met with static build using PCRE2, so it's wrong.

Thanks for the reminder, I have addressed this issue with the following pr: #335
