Remove compile-time dependencies on BasiliskII

ag BasiliskII in this repo yields some concerning entries:

Makefile
16:B2_TOPDIR := ../BasiliskII
37:	cd $(TMPDIR); cvs export -D "$(ISODATE)" BasiliskII SheepShaver

src/MacOSX/XcodeBuildHowTo.txt
15:1. A complete 'macemu' git checkout of SheepShaver and BasiliskII.

Duplicate files as necessary to make these projects stand alone. Open other issues as necessary if we need to create a shared component (as a separate repo).

drop BeOS support

I suggest to drop BeOS support here, because today it would really make more sense to emulate BeOS on macOS rather than to emulate MacOS on BeOS.

And update the project title: SheepShaver works fine on Windows 10:

Merge latest code from @kanjitalk755

Refer to discussion at:
kanjitalk755/macemu#14

Bring in these edits, as they are the most current development of this project.

Set up CHANGELOG.md

Set up a changelog in the format specified by https://keepachangelog.com/en/1.0.0/

This will build on #4 but care must be taken in the initial layout since git history is not available for all the releases it lists.

Set up CI

Set up Travis CI, and others

Recover or re-create `ppc-testresults.dat.bz2`

From doc/PowerPC-Testsuite.md:

It is recommended that you first run the tester on a native PowerPC platform to generate a results file. For reference, here is the [[this>projects/ppctester/files/ppc-testresults.dat.bz2|PowerPC Emulator Tester results file]] I use for SheepShaver. This was generated with AltiVec tests enabled. This is for revision 1.30+ of the file. md5sum is: ''3e29432abb6e21e625a2eef8cf2f0840''.

We should do that, and save the file here for posterity.

drop Amiga support

I suggest to drop Amiga support here, because today it would really make more sense to emulate Amiga on macOS rather than to emulate MacOS on Amiga.

Factor all duplicate files into a shared library.

Creating a shared library seems to be the best path forward for deduplicating the 226 files in BasiliskII that are used directly by Sheepshaver.

Encoded paths

These files contain references to BasiliskII files, found using

ag -l '\.\.\/BasiliskII' SheepShaver | awk '{print "- [ ] `" $1 "`"}'`

Symlinked files

Note to self: this listing doesn't properly handle printing the full source subdirectories

To generate this list of symlinks that need to be deduplicated, it's 3 steps:

# 1. get the repo that we'll be migrating from (assume rev `c3e312f`)
git clone https://github.com/kanjitalk755/macemu

# 2. make a copy, the effect of which is replacing all symlinks
#     with copies of their targets
cp -r macemu macemu_migration

# 3. draw the rest of the owl
cd macemu_migration
git status | grep "^\t" | awk '{print $2}' | xargs -I{} echo "dirname {}" | sh | sort | uniq | xargs -I{} echo "cd ../BasiliskII && ls -l {}/*" | sh | grep -- "->" | awk '{print "- [ ] " $9 " " $10 " " $11}'

git status |grep deleted| grep "^\t" | awk '{print "cd ../BasiliskII && ls -ld  " $2}' | sh | awk "{print \"sh -c 'cd \" \$9 \" && find . -type f | xargs -I{} echo \\\"\" \$9 \"/{} \" \$11 \"/{}\\\" '\" }"  | sh | sed -e 's|/./|/|g' | awk '{print "- [ ] `" $1 "` `" $2 "`"}'

Rewrite documentation

At minimum, the following changes are needed:

Convert document to markdown format
Split README.md into more relevant parts
- GETTINGSTARTED.md - how to configure your environment
- CONTRIBUTING.md - how to develop, test, submit changes, etc
- TROUBLESHOOTING.md - possible gotchas
