if usrsctp support android

[zuobeixing]

Hello，Usrsctp's readme say : SCTP stack supporting FreeBSD, OpenBSD, Linux, Mac OS X and Windows.
Android was not mentioned. So I want to know if usrsctp can be used in android system and how can I useed in android system between two hosts?

Android doesn't support pthread_cancel which usrsctp depends on. I'm also looking for a workaround for this

[alvestrand]

usrsctp was used in WebRTC, which runs on Android, until we switched to dcSCTP. So some workaround was found (but I don't know what it is, or whether or not it was WebRTC specific).

It turns out usrsctp only depends on pthread_cancel in the sample programs. You can turn that off by using
-Dsctp_build_programs=0 and then I was able to build it for Android

If you use the callback-based approach (usrsctp_set_upcall), you can also disable sctp_inet and sctp_inet6 to get rid of some compile issues for older Android versions.
