External dependencies in copied format units

These references were inherited from the Allfix tree and need to be resolved during the format-by-format refactor pass.

ma.fmt.pkt.pas

Currently uses: msgunit, netaddrs, aftypes.

Needs from msgunit:

• PktHeader — 58-byte FTN packet header record
• PktRecord — per-message header record inside a packet
• PacketRecord — high-level parsed message with kludges, address parts, flavours, etc.
• FlavourType, FlavourTypeSet, DateTimeArray

Plan:

• Move PktHeader + PktRecord into ma.fmt.pkt.pas itself (packet-only).
• Move PacketRecord, FlavourType, FlavourTypeSet, DateTimeArray into ma.types.pas so other backends can use them where needed.
• Drop the msgunit / netaddrs / aftypes uses clauses.

ma.fmt.wildcat.pas + ma.fmt.wcutil.pas

Currently use the WildCat SDK (WcType, WcMsgDb, WcUserDb, WcGlobal, WcMisc, WcDb, Os2Comp, DosUtil, p_System).

Plan:

• Treat the WC SDK as an optional dependency. Wrap the entire backend in {$IFDEF WILDCAT4} so builds without the SDK still link.
• Document in README.md that Wildcat support requires the WC SDK source on the FPC search path.

include.inc

Allfix sources start with {$I include.inc}. Our copied units no longer have that on the search path (we deliberately want the new lib to be self-contained). Plan during refactor:

• Replace each {$I include.inc} with explicit {$mode objfpc}{$H+} plus any other compiler switches the unit actually needs (most don't need more than mode + $H+).
• Drop WILDCAT4, EXECSWAP, UNI and other Allfix-specific defines.
