Samrat Man Singh	563fb8e43d	Implement dup and close for stdin/stdout/stderr ... Support F_DUPFD on stdin/stdout/stderr Enable `close`-ing stdin/stdout/stderr For `dup`, check if FD is `File` first If not, clone the appropriate standard IO stream Merge POSIX `close` and `dup` tests into same module Also, add assertion that `write` on a closed FD returns an error. Add `dup` as FileDescriptor trait fn Also: - Fix `close` so it drops `self` instead of reference to it - Remove FD clamping in insert_fd_with_min_fd, since FDs 0-2 can be closed Fix fs_libc tests Make error message when closing stdin/out/err more specific Return io::Result from `FileDescriptor::dup` Change error message when closing stdin/out/err Refactor `FileDescriptor::dup` impl for `FileHandle` Remove empty line	2020-09-09 23:26:33 +05:30

Samrat Man Singh	bea7113eb8	Add impl FileDescriptor for stdin, stdout, stderr ... - Use `FileDescriptor::read` for stdin reads - Use `FileDescriptor::write` for stdout/err writes - Handle stdout/err reads in `FileDescriptor::read`	2020-08-04 01:14:52 +05:30
