This reverts commit e64ab3c675.
This was causing incorrect conversion of strings "0x..." to pointers on systems
like Solaris/ILLUMOS.
And as a side effect, buffers were sometimes empty in weechat relay clients
like glowing-bear.
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.
Some parameters of command `/script` were renamed in commit
85b5bacfe3 but the default mouse keys were not
changed and still using the old parameters names.
