Log Message:
Report file-database write failures instead of failing silently

A file directory whose .sid index has been truncated (the status header counting more files than the index actually holds) causes
smb_new_msghdr() to reject every new record with SMB_ERR_FILE_LEN. That
state went unnoticed here until six file bases had quietly stopped
accepting uploads: a single terminal session transferred 64 files
totalling 2.6 GB, created no records at all, and logged neither an error
nor the usual "U+ uploaded" lines.

sbbs_t::uploadfile() passed NULL for addfile()'s result argument and
returned false with no bputs() and no log entry, so a database failure
was indistinguishable from success to every caller. It also credited
the upload before attempting the add: logon_ulb/logon_uls and inc_upload_stats() ran unconditionally and were never rolled back, which
is why the session footer reported 64 uploads that did not exist.

Audited every caller of addfile(), updatefile() and removefile(), and
fixed the sites that discarded the outcome:

- uploadfile(): report the failure via errormsg(), and only credit the
upload once the record is actually in the database.
- listfileinfo(): check the add-to-offline-directory result.
- editfilename(), editfiledesc(), editfileinfo(): each returned the
updatefile() result as a bool that also encodes "user aborted" and
"nothing changed", so no caller could distinguish a write failure from
either. Report inside the function instead.
- FTP DELE: the file is unlinked before its record is removed, so an
unchecked removefile() leaves a record with no file behind it.
- user_downloaded_file(): same unlink-then-remove ordering; when the
record cannot be removed, return false rather than falling through and
updating a dangling record. Its callers in download.cpp and
websrvr.cpp now check the result.

The FTP upload path and sbbs_t::movefile() already handled this
correctly and were used as the model.
