src/protocol/smb/smb.c: Added #error directives so that this
vulnerable code cannot be accidentally compiled in.
features.conf: Disable CONFIG_SMB by default and explain why.
configure.in: If the user set CONFIG_SMB in features.conf or
--enable-smb in the command line, disable them and warn the user.
(This commit combines f915c31127 and
388de7bd65 from ELinks 0.12.GIT.)
Either set CONFIG_SM_SCRIPTING in features.conf or pass to ./configure the
option --disable-sm-scripting. Now scripting is also enabled when needed
and not only if some other scripting backend is enabled.
Remove some remnants of SEE scripting backend.
