pingpong: use a dynbuf for the *_pp_sendf() function

2020-09-23T07:37:18+00:00

... reuses the same dynamic buffer instead of doing repeated malloc/free
cycles.

dynbuf: offer Curl_dyn_vaddf

2020-09-23T07:21:36+00:00

dynbuf: make *addf() not require extra mallocs

2020-09-23T06:54:42+00:00

... by introducing a printf() function that appends directly into a
dynbuf: Curl_dyn_vprintf(). This avoids the mandatory extra malloc so if
the buffer is already big enough it can just printf directly into it.

Since this less-malloc version requires tthe use of a library internal
printf function, we only provide this version when building libcurl and
not for the dynbuf code that is used when building the curl tool.

Closes #5998

KNOWN_BUGS: Unable to use PKCS12 certificate with Secure Transport

Closes #5403

pingpong: remove a malloc per Curl_pp_vsendf call

2020-09-22T21:13:26+00:00

This typically makes 7-9 fewer mallocs per FTP transfer.

Closes #5997

symbian: drop support

2020-09-22T13:14:12+00:00

The OS is deprecated. I see no traces of anyone having actually built
curl for Symbian after 2012.

The public headers are unmodified.

Closes #5989

test1297: verify GOT_NOTHING with http proxy tunnel

2020-09-22T08:54:42+00:00

http_proxy: do not count proxy headers in the header bytecount

2020-09-22T08:54:34+00:00

... as that counter is subsequently used to detect if nothing was
returned from the peer. This made curl return CURLE_OK when it should
have returned CURLE_GOT_NOTHING.
