The exists('g:loaded_foo') convention is rather common, and may be
relied upon in some cases. It's also very unlikely that a user or plugin
has any reason to set g:loaded_foo to zero, so the principle of least
surprise can be brushed aside here.

- Do not exclude any directories from `find` search, remove dumps before tests
instead.
- Install `apport` on travis so that linux tests should produce core dumps
(based on information from travis-ci/travis-ci#3754, not sure whether it still
applies).
- Check cores in lua so that one has an idea which test is failing exactly. Do
this only 10% of time on linux because traversing the file system is slow.
Unit tests are still not touched, though it is what `app` argument in
`check_cores` is for.
TODO? consider using `find`, it may be faster. Consider retiring `os.execute`,
dealing with escaping is bad.
We must invoke src/nvim/testdir/Makefile directly.
Explained in 3d1084f264:

If we could run `oldtest` with CMake, we would not need to do this. Need
USES_TERMINAL feature (CMake 3.2+) for that.
- Add support for TEST_FILE to the `oldtest` target, for consistency
with the busted/lua tests.
Caveat: with the busted/lua tests TEST_FILE takes a full path, whereas
for `oldtest` it must be "test_foo.res".
- Add support for NVIM_PRG, again so that all test-related targets are
consistent.
- Use consistent name for NVIM_PRG. But still need to support NVIM_PROG
for QuickBuild CI.
Note: The `oldtest` target is driven by the top-level Makefile, because
it requires a TTY. CMake 3.2 added a USES_TERMINAL flag to
add_custom_target(). But we support CMake 2.8...
add_custom_target(oldtest
COMMAND make clean
COMMAND make NVIM_PRG=$<TARGET_FILE:nvim> $ENV{MAKEOVERRIDES}
DEPENDS nvim
WORKING_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/src/nvim/testdir"
USES_TERMINAL true
)
Does not actually matter for most uses, but critical for mark&sweep garbage
collector.

Steps to reproduce:
Compile fb9745785226c3251d4c40e84abe7d031183929a with:
CC=clang CFLAGS=" -O0 -g -DEXITFREE " cmake .. -DMIN_LOG_LEVEL=0 -DCMAKE_BUILD_TYPE=Debug -DBUSTED_OUTPUT_TYPE=utf
-DCMAKE_INSTALL_PREFIX=$PWD/root -DJEMALLOC_USE_BUNDLED=1 -DCLANG_ASAN_UBSAN=ON -DPREFER_LUAJIT=false
Directory `crash` contains:
1. unite directory with be09b0e578
2. vimfiler directory with 72c37e897d
3. `init.vim` with a single line which sets `&rtp` to the above two directories (absolute path).
bin/nvim -u ../crash/init.vim -i NONE --headless -s <(<<< $':split\n:VimFiler\n\C-ww:call garbagecollect()\n\C-w\C-w\C-w')

Problem: Two test files for increment/decrement.
Solution: Move the old style test into the new style test. (Hirohito
Higashi, closesvim/vim#881)

Problem: No test for what 7.4.1948 fixes.
Solution: Add a test. (Hirohito Higashi, closesvim/vim#880)

Some adjustments had to be made from upstream since nvim always uses
utf-8 internally.
* Removed the 'set encoding=cp932' line from the test
* Adjusted the expected values for getpos(), since the number of bytes
is different in utf-8
Problem: Using the system default encoding makes tests unpredictable.
Solution: Always use utf-8 or latin1 in the new style tests. Remove setting
encoding and scriptencoding where it is not needed.
