- Fix a bug in dealing with paramaterized tests where the name is it self a macro expansion.
- Add a compile time check to ensure that the parameters to TEST_P and INSTANTIATE_TEST_SUITE_P are not empty. The above fix causes some compilers to fail in that case and even where it works, it's likely to result in technically invalid code by virtue of creating reserved identifiers:

Fix the O(n^2) number of instantiations in ElemFromList.
It is now O(n). It still has O(1) instantiation depth.

Add a compile time check to ensure that the parameters to TEST_P and INSTANTIATE_TEST_SUITE_P are not empty. Some compilers already fail in that case and, even where it works, it's likely to result in technically invalid code by virtue of creating reserved identifiers:

The change makes implicit assumptions on the layout of the install
tree, which is going to break in many ways.

The correct solution is to use the `PKG_CONFIG_SYSROOT_DIR` variable
to inject the cross-compiled sysroot into `-I` and `-L` paths.

Add an announcement about taking a dep on Abseil soon

Add a compile time check to ensure that the parameters to TEST and TEST_F are not empty

Use a more portable path for Android to write temp files to.

/sdcard is *not* guaranteed to be available, but /data/local/tmp is.

In some emulated situations, /sdcard may not be mounted, may not be R/W, or
mounting may be delayed until *after* the test process begins.

This is fairly common location to use. See e.g.:
https://reviews.llvm.org/D9569
