Re: Refactor backup related code (was: Is it correct to say, "invalid data in file \"%s\"", BACKUP_LABEL_FILE in do_pg_backup_stop?)

This commit introduced BackupState struct. The comment of
do_pg_backup_start says that:

> * It fills in backup_state with the information required for the backup,

And the parameters are:

> do_pg_backup_start(const char *backupidstr, bool fast, List **tablespaces,
>                    BackupState *state, StringInfo tblspcmapfile)

So backup_state is different from both the type BackupState and the
parameter state.  I find it annoying.  Don't we either rename the
parameter or fix the comment?

The parameter "state" sounds a bit too generic. So I prefer to rename
the parameter to backup_state, as the attached.

What do you think about this?

regards.
