PR62199: add worker parameter ResponseFieldSize to mod_proxy

Submitted By: Hank Ibell
Committed By: covener

add log id for r1828926

core: Add and handle AP_GETLINE_NOSPC_EOL flag in ap_rgetline_core().

This tells the ap_getline() family of functions to consume the end of line
when the buffer is exhausted.

PR 62198.

mod_proxy_http: make use of AP_GETLINE_NOSPC_EOL in ap_proxygetline().

Fixes response header thrown away after the previous one was considered too
large and truncated.

PR 62196.

core: forward flags to recursive/folding call to ap_rgetline_core().

We still need them when folding, other than AP_GETLINE_FOLD itself of course.

mod_proxy_http: follow up to r1829573: remain EBCDIC friendly.

Keep using ap_rgetline() as before r1829573, since ap_rgetline_core() is
EBCDIC agnostic.
