curl: enable threaded resolver
Multi-threaded applications using libcurl crash
on DNS timeouts when built using OE.
The reason is as follows:
By default, libcurl implements DNS timeouts using a
timer (alarm()) and a pair of setjmp()/longjmp().
This approach is unsafe in multi-threaded applications
for various reasons, as e.g. explained in the relevant
man-pages.
To avoid this, libcurl can be compiled with a built-in
threaded resolver, or against the c-ares asynchronous
resolver library.
To keep extra dependencies to a minimum, and to mimic
other distributions (debian at least), and because
c-ares is not available in OE-core, add a PACKAGECONFIG
to be able to enable use of of the built-in threaded
resolver and enable it by default.
