curl: support --enable-curl=tiny option.

[philljj]

Description

A tiny change that allows wolfSSL x509 small + HAVE_CURL to support tiny-curl-8.4.0 default build.

Building

Build wolfssl with:

./configure --enable-curl=tiny && make && sudo make install

Build tiny-curl-8.4.0 with:

./configure --with-wolfssl && make

Testing

Result of tiny-curl make test with wolfssl --enable-curl=tiny:

test 3201...OK (1291 out of 1291, remaining: 00:00, took 1.071s, duration: 37:26)
TESTDONE: 1646 tests were considered during 2247 seconds.
TESTDONE: 1189 tests out of 1193 reported OK: 99%

TESTFAIL: These test cases failed: 1119 1165 1167 1474

The same with normal wolfssl --enable-curl on master:

test 3201...OK (1407 out of 1407, remaining: 00:00, took 1.074s, duration: 38:01)
TESTDONE: 1646 tests were considered during 2282 seconds.
TESTDONE: 1303 tests out of 1307 reported OK: 99%

TESTFAIL: These test cases failed: 1119 1165 1167 1474 

Notes

• --enable-curl=tiny will not build normal libcurl, because SSL_CTX_*_cert_store symbols are missing.
• --enable-opensslextra can build both normal libcurl, and tiny-curl.

Retest this please, AgentOfflineException exception:.

I presume this is for SSL_CTX_set1_curves_list ?

In later versions of curl we have changed that to use the more appropriate wolfSSL_CTX_set1_curves_list. Would that make any difference for the build?

Correct!

The naming is fine, because we remap the openssl to wolfssl names in wolfssl/openssl/ssl.h anyways.

The deal is, on wolfssl master:

• --enable-opensslextra=x509small: SSL_CTX_set1_curves_list is missing, tiny-curl won't build.
• --enable-opensslextra=x509small + HAVE_CURL: has the missing symbol, but wolfssl won't build.

On this PR branch:

• --enable-opensslextra=x509small + HAVE_CURL: wolfssl and tiny-curl build.

This PR also adds --enable-curl=tiny that is equivalent to --enable-opensslextra=x509small + HAVE_CURL.
