At the moment, building WeeChat triggers several thousand -Wstrict-prototypes
diagnostics. This is due to its source code using an empty argument list for
functions and function pointers that take no arguments, instead of explicitly
declaring that they take no arguments by using a void list.
This commit replaces all empty argument lists with a void list.
Note that Ruby's headers also suffer the same problem, which WeeChat can't
do anything to fix. Thus, building WeeChat with the Ruby plugin enabled
will still issue approximately 30 such diagnostics.
Bump the requirement to v7.47.0 as available in Ubuntu 16.04 (7.47.0)
and Debian 10 (7.64.0). It was released around 9 years ago and any
remotely supported distribution has newer version.
As result we can adjust the tools/check_curl_symbols.py script to omit
the ~70% of the guards and simplify the code base.

The curl option handling seems to be non-functional since it suffers
from two distinct issues. The regular expression tries to match options
that we're not interested in and the symbol name is lacking the proper
prefix.
Adjust to match only on what we need and construct the name
appropriately... Fix the issues flagged by the updated script.
