Log Message:
Pull up revisions 1.19-1.20 (requested by manu in ticket #1064)
 ftpd was unable to service the pwd request once you entered a directory
 without search permission. This confused some ftp clients.

 We fix this problem by maitaining a cached path when getcwd() does not
 work. The symbolic links and ../ are resolved in the cached path, and it
 is finnally checked for accuracy by comparing ./ and the cached path
 with stat (device and inode comparison). If the comparison fails, pwd
 fails as it did before, and if the comparison succeeds, the cached path
 is displayed.

 If paths are too long, we should just compare ./ with a truncated path
 and fail, thus making pwd displaying an error as it did before.
