[PECL-DEV] New extension "concurrent"

[Bastian Schneider]

Hello PECL,

I would like to introduce a new extension called "concurrent" for the 
pecl. "Concurrent" is a fork of the "pthreads" extension, which has 
since been canceled and archived (see 
https://github.com/krakjoe/pthreads/issues/929). pthreads was and is 
extremely important for many developers, since there is no extension 
with a comparable range of functions. The pthreads code is compatible up 
to php 7.3, however the last release was in 2016 for php 7.1 or 7.2. I 
have been following the development since 2013 and have been using the 
extension fundamentally for many of my projects since then. I have been 
a maintainer since 2017. Hence my interest in continuing the development 
of this extension, which has so far been unique for php.

"concurrent" is supposed to provide two branches. One branch remains 
backward compatible with pthreads and is only intended for compatibility 
with php 7.4, future php versions and bug fixes. In the second branch 
new features should come, a revised API, namespacing and more. I am 
currently working on the fork on github, which should be public until 
January.

What do you think? I would be happy if "concurrent" makes it into the 
pecl. I look forward to your feedback.

Thanks,
Bastian
