1409: unistd: Increase maximum passwd/group buffer to 1MB r=asomers a=geofft We have one UNIX group that contains most of our users whose size is about 20 kB, so `Group::from_name` is failing with ERANGE. The discussion on PR #864 suggests that 1 MB is a reasonable maximum - it follows what FreeBSD's libc does. (glibc appears to have no maximum on the _r function and will just double the buffer until malloc fails, but that's not particularly Rusty.) Co-authored-by: Geoffrey Thomas <geofft@twosigma.com>

1407: Fix test_vsock failure on VMADDR_CID_LOCAL testing and re-enable it r=asomers a=stefano-garzarella Starting from Linux 5.6, `VMADDR_CID_LOCAL` is supported to do local communication (loopback device). Before Linux 5.6 it was called `VMADDR_CID_RESERVED` and was not supported, so we could expect an `EADDRNOTAVAIL`, but now this address is supported and handled by the 'vsock_loopback' kernel module loaded automatically if no other vsock transports are loaded.

1390: pty: Make forkpty() unsafe r=asomers a=tavianator After the child returns from a fork() of a multi-threaded process, it is undefined behaviour to call non-async-signal-safe functions according to POSIX.

1381: Close file descriptor on drop in TimerFd r=asomers a=crdumoul This change closes the TimerFd file descriptor on drop. Note that the TimerFd will no longer be `Clone` or `Copy`. Since it has a destructor it can't be `Copy`, and if it were `Clone` you could end up trying to use a closed TimerFd, or double-closing the file descriptor. Addresses #1379.
