// ParseFTPLine() parses line from an FTP LIST command.

//
// Arguments:
// 'line': line of FTP data connection output. The line is assumed
// to end at the first '\0' or '\n' or '\r\n'.
// 'state': a structure used internally to track state between
// lines. Needs to be bzero()'d at LIST begin.
// 'result': where ParseFTPList will store the results of the parse
// if 'line' is not a comment and is not junk.
//
// Returns one of the following:
// 'd' - LIST line is a directory entry ('result' is valid)
// 'f' - LIST line is a file's entry ('result' is valid)
// 'l' - LIST line is a symlink's entry ('result' is valid)
// '?' - LIST line is junk. (cwd, non-file/dir/link, etc)
// '"' - its not a LIST line (its a "comment")
//
// It may be advisable to let the end-user see "comments" (particularly when
// the listing results in ONLY such lines) because such a listing may be:
// - an unknown LIST format (NLST or "custom" format for example)
// - an error msg (EPERM,ENOENT,ENFILE,EMFILE,ENOTDIR,ENOTBLK,EEXDEV etc).
// - an empty directory and the 'comment' is a "total 0" line or similar.
// (warning: a "total 0" can also mean the total size is unknown).
//
// ParseFTPList() supports all known FTP LISTing formats:
// - '/bin/ls -l' and all variants (including Hellsoft FTP for NetWare);
// - EPLF (Easily Parsable List Format);
// - Windows NT's default "DOS-dirstyle";
// - OS/2 basic server format LIST format;
// - VMS (MultiNet, UCX, and CMU) LIST format (including multi-line format);
// - IBM VM/CMS, VM/ESA LIST format (two known variants);
// - SuperTCP FTP Server for Win16 LIST format;
// - NetManage Chameleon (NEWT) for Win16 LIST format;
// - '/bin/dls' (two known variants, plus multi-line) LIST format;
// If there are others, then I'd like to hear about them (send me a sample).
//
// NLSTings are not supported explicitely because they cannot be machine
// parsed consistently: NLSTings do not have unique characteristics - even
// the assumption that there won't be whitespace on the line does not hold
// because some nlistings have more than one filename per line and/or
// may have filenames that have spaces in them. Moreover, distinguishing
// between an error message and an NLST line would require ParseList() to
// recognize all the possible strerror() messages in the world.
