This enables of the use of AI_* definitions in the Windows headers,
specifically AI_ADDRCONFIG, which fixes an issue with libevent and
ipv6 on Windows.
It also aligns with what we define in configure when building Core.
(cherry picked from commit eb6b73540d1ee7ff5a6874dd0e35f9b30b68e3b8)
libevent uses getaddrinfo when available, and falls back to gethostbyname
Windows has both, but gethostbyname only supports IPv4
libevent fails to detect Windows's getaddrinfo due to not including the right headers
This patches libevent's configure script to check it correctly
(cherry picked from commit 03e056edcd1a7f7197a29068c52fa33fce12f7d7)
By blanket passing --disable-dependency-tracking to all depends packages
we end up with some warnings like:
configure: WARNING: unrecognized options: --disable-dependency-tracking
So instead, only pass it to packages that understand it.
Related to https://github.com/bitcoin/bitcoin/issues/16354.
We use pkg-config where we can, which generally replaces libtool at a
higher level and does not have the same downsides as libtool. These
archives sit in our depends tree with no purpose and pollute the final
bitcoin build with massive overlinking.
Add a patch that seems to be necessary for compatibilty of libevent
2.0.22 with recent mingw-w64 gcc versions (at least GCC 5.3.1 from Ubuntu
16.04).
Without this patch the Content-Length in the HTTP header ends up as
`Content-Length: zu`, causing communication between the RPC
client and server to break down. See discussion in #8653.
