macOS osx/ios dynamic framework support (#466)

Browse Source 
* OSX bundle support

* Disable framework by default, and fix domain name typo

* Remove info.plist, add efx.h for framework public header

* Fix osx/ios framework PUBLIC_HEADER doesn't work

* Refine comment message

* Auto set CFBundleShortVersionString by var LIB_VERSION

* Set CFBundleVersion from git commit count

* Use space to separate elements in a list

* Specific framework name to variable 'IMPL_TARGET'

* Solve cmake try_compile failed with code sign, and disable framework code sign

* Make ios travis to build dynamic framework bundle by default

* Update ios.toolchain.cmake

Since we solve code sign issue for cmake to generate dynamic framework xcode project, enable strict try_compile by default

* Remove MAKE_CXX_EXTENSIONS from travis-ci

* Combined flat lib armv7;arm64 support

* Remvoe ios.toolchain.cmake since we don't need
[skip appveyor] [skip travis]

* Sets framework name to soft_oal,
avoid ambiguous with system OpenAL.framework

* Fix missing BUNDLE, FRAMEWORK's DESTINATION
Build osx/ios dynamic framework required them.

* Use @rpath instead fullPath to mac local disk

https://github.com/libjpeg-turbo/libjpeg-turbo/commit/c80ddef7a4ce21ace9e3ca0fd190d320cc8cdaeb

* CMake, use TRUE for bool value

* Don't disable examples, utils, install

* Make ALSOFT_OSX_FRAMEWORK for APPLE spec

* Remove unused flag and more clearly comment

* More clearly comment for solve armv7 target issue

# INFORMATION / HELP
#
# The following arguments control the behaviour of this toolchain:
#
# PLATFORM: (default "OS")
# OS = Build for iPhoneOS.
# OS64 = Build for arm64 iphoneOS.
# OS64COMBINED = Build for arm64 x86_64 iphoneOS. Combined into FAT STATIC lib (supported on 3.14+ of CMakewith "-G Xcode" argument ONLY)
# SIMULATOR = Build for x86 i386 iphoneOS Simulator.
# SIMULATOR64 = Build for x86_64 iphoneOS Simulator.
# TVOS = Build for arm64 tvOS.
# TVOSCOMBINED = Build for arm64 x86_64 tvOS. Combined into FAT STATIC lib (supported on 3.14+ of CMake with "-G Xcode" argument ONLY)
# SIMULATOR_TVOS = Build for x86_64 tvOS Simulator.
# WATCHOS = Build for armv7k arm64_32 for watchOS.
# WATCHOSCOMBINED = Build for armv7k arm64_32 x86_64 watchOS. Combined into FAT STATIC lib (supported on 3.14+ of CMake with "-G Xcode" argument ONLY)
# SIMULATOR_WATCHOS = Build for x86_64 for watchOS Simulator.
#
# CMAKE_OSX_SYSROOT: Path to the SDK to use. By default this is
# automatically determined from PLATFORM and xcodebuild, but
# can also be manually specified (although this should not be required).
#
# CMAKE_DEVELOPER_ROOT: Path to the Developer directory for the platform
# being compiled for. By default this is automatically determined from
# CMAKE_OSX_SYSROOT, but can also be manually specified (although this should
# not be required).
#
# DEPLOYMENT_TARGET: Minimum SDK version to target. Default 2.0 on watchOS and 9.0 on tvOS+iOS
#
# ENABLE_BITCODE: (1|0) Enables or disables bitcode support. Default 1 (true)
#
# ENABLE_ARC: (1|0) Enables or disables ARC support. Default 1 (true, ARC enabled by default)
#
# ENABLE_VISIBILITY: (1|0) Enables or disables symbol visibility support. Default 0 (false, visibility hidden by default)
#
# ENABLE_STRICT_TRY_COMPILE: (1|0) Enables or disables strict try_compile() on all Check* directives (will run linker
# to actually check if linking is possible). Default 0 (false, will set CMAKE_TRY_COMPILE_TARGET_TYPE to STATIC_LIBRARY)
#
# ARCHS: (armv7 armv7s armv7k arm64 arm64_32 i386 x86_64) If specified, will override the default architectures for the given PLATFORM
# OS = armv7 armv7s arm64 (if applicable)
# OS64 = arm64 (if applicable)
# SIMULATOR = i386
# SIMULATOR64 = x86_64
# TVOS = arm64
# SIMULATOR_TVOS = x86_64 (i386 has since long been deprecated)
# WATCHOS = armv7k arm64_32 (if applicable)
# SIMULATOR_WATCHOS = x86_64 (i386 has since long been deprecated)
#
# This toolchain defines the following variables for use externally:
#
# XCODE_VERSION: Version number (not including Build version) of Xcode detected.
# SDK_VERSION: Version of SDK being used.
# CMAKE_OSX_ARCHITECTURES: Architectures being compiled for (generated from PLATFORM).
# APPLE_TARGET_TRIPLE: Used by autoconf build systems. NOTE: If "ARCHS" are overridden, this will *NOT* be set!
#
# This toolchain defines the following macros for use externally:
#
# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE XCODE_VARIANT)
# A convenience macro for setting xcode specific properties on targets.
# Available variants are: All, Release, RelWithDebInfo, Debug, MinSizeRel
# example: set_xcode_property (myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1" "all").
#
# find_host_package (PROGRAM ARGS)
# A macro used to find executable programs on the host system, not within the
# environment. Thanks to the android-cmake project for providing the
# command.
