Nick Alexander 1cb1847aa6 Part 5: Make existing TermBuilder actually build Entity instances. 
There are a few tricky details to call out here.  The first is the
`TransactableValueMarker` trait.  This is strictly a marker (like
`Sized`, for example) to give some control over what types can be used
as value types in `Entity` instances.  This expression is needed due
to the network of `Into` and `From` relations between the parts of
valid `Entity` instances.  This allows to drop the `IntoThing`
work-around trait and use the established patterns.  (Observe that
`KnownEntid` makes this a little harder, due to the cross-crate
consistency restrictions.)

The second is that we can get rid `{add,retract}_kw`, since the
network of relations expresses the coercions directly.

The third is that this commit doesn't change the name `TermBuilder`,
even though it is now building `Entity` instances.  This is because
there's _already_ an `EntityBuilder` which fixes the `EntityPlace`.
It's not clear whether the existing entity building interface should
be removed or whether both should be renamed.  That can be follow-up.

Development flow for Mentat FFI

Android SDK

Android Mentat SDK is one of two first-party consumers (the other one being iOS Mentat SDK).

Binaries produced by cargo build ... are symlinked from within the SDK, and a number of target-specific libmentat_ffi.so binaries are bundled together and distributed with the SDK.

There is a build script at <mentat_root>/scripts/android_build.sh which knows how to cross-compile mentat_ffi for various Android targets.

  • ./<mentat_root>/scripts/android_build.sh - compiles for all supported targets
  • ./<mentat_root>/scripts/android_build.sh x86 - compiles for x86
  • ./<mentat_root>/scripts/android_build.sh x86 arm - compiles for x86, arm

General development flow while working on the Android SDK is:

  • (pre) compile for all targets, if you've never done so
  • make changes to mentat_ffi and/or mentat
  • re-compile mentat_ffi binaries using ./android_build.sh x86. During development it's faster to compile just for the target which matches your emulator, e.g. x86
  • make corresponding changes in the Android SDK, try them out from within the bundled sample project
  • since binaries are symlinked, no manual copy step is necessary for the Android SDK to pick up the changes

iOS SDK

TODO, contribute via issue #732.
