echoing PR: https://github.com/Azure/azure-uamqp-python/pull/193 with more clean commit history

to compile the latest c module:

• stdbool/stdint.h missing
  • vendor and include it in the setup.py
• Fix C89 compilation error
  • Syntax fix
  • src/vendor/azure-uamqp-c/deps/azure-c-shared-utility/adapters/x509_schannel.c
  • src/vendor/azure-uamqp-c/deps/umock-c/src/umocktypes_wcharptr.c
  • src/vendor/azure-uamqp-c/deps/azure-c-shared-utility/src/constbuffer_array_batcher.c
  • Change compilation warning level from W4 to W3 on MSVC to address warning treated as error
  • Method "CertVerifyCertificateChainPolicy" (etc.) causes warning C4306 type case: conversion from int to LPCSTR, and this compilation warning is treated as error
  • Exclude srw_lock module which is not used by any module but causing trouble to compiler
  • It calls "interlocked64" operations which are not able to be compiled with VC9 X86
• Windows SDK on Python2.7
  • In setup.py, utilize "get_latest_windows_sdk" to find the latest shared include dir (which includes header files)
  • In "get_generator_flags", append command to tell Cmake whether to use the latest WinSDK and Where is the include
  • In CMakeLists.txt, check flag and include directory
