Renamed readx/writex to ReadFdExactly/WriteFdExactly respectively. These read/write a full fixed-size buffer. If the whole buffer cannot be read/written, these functions return an error. Rename write_string to WriteStringFully. Move the TEMP_FAILURE_RETRY definition in sysdeps.h out of the !Windows section. It seems Windows won't actually interrupt a call, but it's easier to just define it than to #ifdef each call. Change-Id: Ia8ddffa2a52764a2f9a281c96c937660e002b9b9
