2022-06-23 Add runtime fallback for GRND_INSECURELaurent Bercot
The grndinsecure sysdep is only build-time tested and returns yes if the kernel headers declare GRND_INSECURE. That is a problem because the kernel headers are most likely provided by the toolchain and do not reflect the exact capabilities of the run-time kernel. If the run-time kernel doesn't support that option, getrandom() fails. That made random_buf_early() busyloop. To avoid that, we now fallback to random_devurandom() as an implementation of random_buf_early() if getrandom() fails when used with GRND_INSECURE. This adds a slight amount of overhead to random_buf_early(), so it's probably better to just disable the sysdep at build time if you're making binaries that will run on older kernels.

2020-12-09 Get rid of webipc.h and DJBUNIX_FLAG_*Laurent Bercot
Decent semantic header separation is hard. It's always an ongoing process. Here socket.h always included webipc.h for listen(), and webipc.h always included djbunix.h for socket_internal() and socketpair_internal(). That's ugh. Just move all the socket stuff into one socket header. Of course, djbunix.h is still needed most of the time for fd_close() and other operations on fds, but those are generic anyway. Also, O_CLOEXEC exists everywhere now, so we can use it as well as O_NONBLOCK instead of redefining the flags in djbunix.h.
