There is information about the compiled-in SSL backends that is really no concern of any code other than the SSL backend itself, such as which function (if any) implements SHA-256 summing. And there is information that is really interesting to the user, such as the name, or the curl_sslbackend value. Let's factor out the latter into a publicly visible struct. This information will be used in the upcoming API to set the SSL backend globally. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> |

Include files for libcurl, external users.
They're all placed in the curl subdirectory here for better fit in any kind
of environment. You must include files from here using...
#include <curl/curl.h>
... style and point the compiler's include path to the directory holding the
curl subdirectory. It makes it more likely to survive future modifications.
NOTE FOR LIBCURL HACKERS
* If you check out from git on a non-configure platform, you must run the
appropriate buildconf* script to set up files before being able of compiling
the library.
* We cannot assume anything else but very basic compiler features being
present. While libcurl requires an ANSI C compiler to build, some of the
earlier ANSI compilers clearly can't deal with some preprocessor operators.
* Newlines must remain unix-style for older compilers' sake.
* Comments must be written in the old-style /* unnested C-fashion */
To figure out how to do good and portable checks for features, operating
systems or specific hardwarare, a very good resource is Bjorn Reese's
collection at http://predef.sf.net/
