fuzzing protocols not supported in the build

[bagder]

Currently we build a set of different fuzzers for different protocols and we build a generic one for "all" protocols.

We build several specific ones for protocols that can't be fuzzed because our build does not build with necessary third party libraries:

• the rtmp* ones need librtmp
• scp and sftp need a SSH library
• ldap(s) need OpenLDAP

Maybe we should just disable those or add additional libraries to the build?

The generic curl_fuzzer builds and specify "all" protocols:

  allowed_protocols =
    "dict,file,ftp,ftps,gopher,gophers,http,https,imap,imaps,"
    "ldap,ldaps,mqtt,pop3,pop3s,rtmp,rtmpe,rtmps,rtmpt,rtmpte,rtmpts,"
    "rtsp,scp,sftp,smb,smbs,smtp,smtps,tftp";

But this also means that it will try a lot of protocols that are not supported in the build as listed above. Should we perhaps remove those unsupported protocols from the list?

iirc openldap was a PITA to build from source, though I was probably trying to do a static build or something. In practice I'm happy to disable protocols that we can't support, though the preference is to try and build those libraries. Might be worth hacking on it to see how hard it would be.
