Pointers to relocatable blocks were being kept and re-used! Now HLock is
correctly used to keep the blocks in place. This is Memory Manager 101.

Elliot Nunn bbb73bc9b7 Use placeholder files to create BuildResults/
Running the Make/CreateBuildResultsFolders script after a clone, or

Elliot Nunn c087445dd0 Correct names of NK Event Group wrapper code
The names of the NanoKernel MP calls made by this 68k ROM library were
found by inspecting the PowerPC MPLibrary, which makes these and many
other MP calls. The document "Adding Multitasking Capability to
Applications Using Multiprocessing Services" gave some background
information. It also helped to determine the function signatures of the
MP calls and of these ROM wrappers.

Elliot Nunn 4204a9c355 Build MMU.lib from sources
The sources needed no changes (how embarrassing), except to remove an
unnecessary dependence on a nonexistent SoundPrivate.a. Lastly.lib had
an incorrect position for SIDESOUNDBUFFER, which has been fixed.

Elliot Nunn 0e4a082eb4 Remove branch islands
The unlinker's new ISLANDGUESS HIDE' option removes autogenerated BSR.L
from the binary dumps and makes tweaks that will cause them to be
regenerated by the linker. MPW's linker seems to have the correct branch
island placement policy, because round-tripping is preserved. When
building from edited sources, there is a remote possibility that the
arrangement of branch islands inside a dumped file will be changed,
disrupting references within that file.

Elliot Nunn 5a0785d5d8 Correctly reverse Standard and Interface libs
Previously these were lumped in with Lastly. Now they are unlinked and
correctly labelled, and Lastly contains only a small amount of PowerPC-
specific code.

Elliot Nunn d4a7b16d8d Declare between-file branches
The unlink tool now REFGUESSes branches between object files, with some
manual guidance. If you patch the ROM enough to change its function
offsets, it should still work fine.

(One potential exception: if the linker needs to put a new "BSR.L"
island module *within* a pre-built object file, that module file's
internal references *may* be disrupted. This situation is fairly
unlikely, but with improved reversal it will be addressed.)

Elliot Nunn 8908c7662c Switch to new unlinker
"DeVectorize" was a hideous several-thousand-line Python script that
split 70% of the ROM into barely passable MPW object files. The new
unlinker, "unlink", produces much nicer files and enjoys a clean
separation of code from data. Using DumpObj, you can get a very readable
listing of a given object file (GoNativeROMLib.o has improved a great
deal). With a bit more work, unlink will be superior to FDisasm for all
68k Mac ROM reversal.

Elliot Nunn 76713a2368 Identify Expansion Bus Manager entry points
The ExpansionBusDispatch trap (AAF3) is implemented in ROM using a
DispatchHelper table. Using a header from the embryonic Expansion Bus Mgr in
CubeE (rather suspect) and from the Universal Interfaces (solid), the names of
24 of the 47 dispatch selectors have been found. This commit updates the
dumped ExpansionBusMgr.lib with new symbol names.

All but two of the 47 dispatch selectors are Vectorized, so this commit also
updates VectorTable.a with selector numbers and, where possible, names. The
two non-Vectorized dispatch selectors (27 and 28) both point to the same 'nop'
function immediately before ExpansionBusDispatch.

Elliot Nunn 26978a00fb Update SANE (PACK 7) and get it building
SANE is the Standard Apple Numeric Environment (a float library deprecated in
favour of the native PowerPC float unit). The only change to the PACK 7
resource was in the vicinity of a _StripAddress call. SANE also had to be
added to the reconstructed Toolbox.make file.

Elliot Nunn 3a7bff43c0 Add RomLink, a bytecode interpreter
The "RomLink" bytecode language can be used to link a tree of binary chunks
into a flat file. The bytecode specifying each binary chunk lives in a
Resource Manager resource. The RomLink's only purpose is to flatten
DeclData.rsrc into a "Slot 0" (motherboard) DeclData, so it seems like
overkill. Nonetheless, DeclData.rsrc is very complicated (and so are its
antecedents, DeclData.r and the include file RomLink).

This implementation is incomplete. It is just enough to build the vestigial
DeclROM that TNT and later machines retain for Open Transport.

Elliot Nunn 269a655a67 Add a script to convert line endings
Git works better with LFs but MPW mostly requires CRs.
ConvertLineEndings acts only on TEXT files, so run SuggestFileTypes
first. Then:

:Make:ConvertLineEndings > "{TempFolder}FixLines" ; "{TempFolder}FixLines"

ConvertLineEndings is both an MPW script and a C program. The script
builds the fast MPW C Tool, and suggests a command that will use the
Tool to fix all the line endings in the repository.

Elliot Nunn 666baba343 Add scripts to make a git-mangled repo buildable
CreateBuildResultsFolders is necessary because git does not track empty
directories (fair enough) despite the build system requiring their presence.

SuggestFileTypes is necessary because git does not track Finder metadata.

Both scripts are flexible in how they are run and robust -- important in a
newly cloned repo.
