Now the function utf8_next_char with an empty string returns NULL instead of
the next char, which is most of the time after an allocated buffer.
And the function utf8_char_size with an empty string now returns 0 instead of
1.
This indirectly fixes a buffer overflow in function eval_string_range_chars
when the input string is empty (for example when doing `/eval -n ${chars:}`).
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.
For now the only supported flag is:
- "stop_on_error": stop execution of callbacks immediately after an
error (ie return code of callback is WEECHAT_RC_ERROR) and return this code
(by default execute all callbacks and return the last return code, or return
WEECHAT_RC_EAT immediately if a callback returns this)
Example:
hook_signal_send("[flags:stop_on_error]my_signal", WEECHAT_HOOK_SIGNAL_STRING, "test");
Bump the requirement to v3.3.0 as available in Ubuntu 16.04 (3.4.10) and
Debian 10 (3.6.7). It was released around 10 years ago and any remotely
supported distribution has newer version.
As result, we can remove hundred+ lines of #ifdef spaghetti code.

Errors from hook_url should be handled by the caller, so don't print
them to the core buffer by default. Only print them when
weechat_debug_core is enabled. This was already the behavior for the
timeout error.
When hook_url fails, add an error_code field in the output in addition
to the error field. This is so the caller can get which error happened
programatically, without having to parse the (possibly translated) error
string.
It uses the same error codes as the return_code in hook_process, and in
addition adds 5 for an error from pthread_create and 6 for a timeout
error. If the error is from pthread_create, an additional field
`error_code_pthread` with the error code from pthread_create is added.
If the error is from curl, an additional field `error_code_curl` with
the error code from curl is added.
The clean of processes with waitpid() is now delayed after the kill(), so that
there are no more zombies.
In addition, this can be done manually if needed with `/sys waitpid`.
