Make the library usable for local testing without Docker on a Mac

[bmoffatt]

Issue #, if available:

Description of changes:

I don't always love using Docker to do local invoke testing, preferring to use a locally built version of https://github.com/aws/aws-lambda-runtime-interface-emulator.

However, this workflow doesn't work for python, as awslambdaric doesn't compile it's native dependencies, instead logging that aws-lambda-cpp doesn't compile on Macs. However, that set of issues should be resolved now after changes like awslabs/aws-lambda-cpp#154 present in newer releases.

This change

• updates the version of aws-lambda-cpp to 0.2.10 from 0.2.6
• removes patch files that have since been upstreamed
• re-works patch files that didn't cleanly re-apply
• allows setup.py to run scripts/preinstall.sh on macOS
• skips the static libcurl build on macOS system installed one should be fine for this usecase.
  • note: the static build does work with some additional configuration, see: a3f9db8#diff-9a81181daf1e1d37a34191f62304f57ec5c3cf1e57203e6259a2f2db175b778e)

My no Docker local testing workflow for this looks something like

Makefile

venv: lambda/requirements.txt
        /usr/bin/python3 -m venv $@

venv/requirements.installed: lambda/requirements.txt venv
        . $$(dirname $@)/bin/activate; pip install -r $<
        touch $@

.PHONY: clean
clean:
        rm -rf venv/

.PHONY: serve
serve: venv/requirements.installed
        @echo "run in another terminal to test:\n\tcurl -XPOST "http://localhost:8080/2015-03-31/functions/function/invocations" -d '{}'"
        . $$(dirname $<)/bin/activate; aws-lambda-rie python3 -m awslambdaric lambda/handler.handler
