WIP: Add support for gemini meta headers

Add gemini protocol support

2020-05-21T22:38:31+00:00

The gemini protocol's "speculative specification" is documented  at the
following URLs:

  https://gemini.circumlunar.space/docs/spec-spec.txt
  gopher://gemini.circumlunar.space/1/docs/spec-spec.txt
  gemini://gemini.circumlunar.space/docs/spec-spec.txt

This patch introduces preliminary support for version 0.11.0 of the
specification, as of March 1st 2020.

tool_paramhlp: fixup C89 mistake

Follow-up to c5f0a9db22.

tool_paramhlp: fixed potentially uninitialized strtol() variable

2020-05-19T06:55:27+00:00

Seems highly unlikely to actually be possible, but better safe than
sorry.

Closes #5417

tool_operate: fixed potentially uninitialized variables

2020-05-19T06:53:41+00:00

... in curl_easy_getinfo() calls. They're harmless but clearing the
variables makes the code safer and comforts the reader.

Closes #5416

setopt: support certificate options in memory with struct curl_blob

2020-05-15T11:03:59+00:00

This change introduces a generic way to provide binary data in setopt
options, called BLOBs.

This change introduces these new setopts:

CURLOPT_ISSUERCERT_BLOB, CURLOPT_PROXY_SSLCERT_BLOB,
CURLOPT_PROXY_SSLKEY_BLOB, CURLOPT_SSLCERT_BLOB and CURLOPT_SSLKEY_BLOB.

source cleanup: remove all custom typedef structs

2020-05-15T06:54:42+00:00

 - Stick to a single unified way to use structs
 - Make checksrc complain on 'typedef struct {'
 - Allow them in tests, public headers and examples

 - Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually
   typedef different types/structs depending on build conditions.

Closes #5338

tool: support UTF-16 command line on Windows

2020-05-14T16:13:36+00:00

- use `wmain` instead of `main` when `_UNICODE` is defined [0]
- define `argv_item_t` as `wchar_t *` in this case
- use the curl_multibyte gear to convert the command-line arguments to
  UTF-8

This makes it possible to pass parameters with characters outside of
the current locale on Windows, which is required for some tests, e.g.
the IDN tests. Out of the box, this currently only works with the
Visual Studio project files, which default to Unicode, and winbuild
with the `ENABLE_UNICODE` option.

curl_multibyte: add to curlx

2020-05-14T16:13:27+00:00

This will also be needed in the tool and tests.

checksrc: enhance the ASTERISKSPACE and update code accordingly

Fine: "struct hello *world"

Not fine: "struct hello* world" (and variations)
