Extend sendFileWithContent() to handle custom content length in basebackup.c
sendFileWithContent() previously got the content length by using
strlen(), assuming that the content given is always a string. Some
patches are under discussion to pass binary contents to a base backup
stream, where an arbitrary length needs to be given by the caller
instead.
The patch extends sendFileWithContent() to be able to handle this case,
where len < 0 can be used to indicate an arbitrary length rather than
rely on strlen() for the content length.
A comment in sendFileWithContent() mentioned the backup_label file.
However, this routine is used by more file types, like the tablespace
map, so adjust it in passing.
