Add an `objc_public_headers` attribute to apple_* rules. This changes the umbrella header, if set, such that it includes all public_headers headers when compiled against c++, and only a subset of headers (objc_public_headers) when compiled against objective c. The main problem this is solving is that we have a main module map for each library. When trying to import *anything* from the framework, it loads the entire module map and every include in the umbrella header. If you put c++-only headers in it, it will try to interpret those without c++ support if you try to include the .h from a .m file. This allows us to have headers that mix (obj)c++ and objc in a single framework. It should also allow us to drop some of the -objc rules we've had to clunkily build out.

Add an `apple_static_library` that lets us map source files to arbitrary relative include paths by creating a link tree, and adding that link tree to the deps of a main library. This also uses apple_library instead of apple_framework as the framework is frankly unnecessary for what we're trying to build for third party deps. Test Plan: Ported fmt locally to use this, and ran `clyde ios build` Tasks: https://app.asana.com/0/1203960884932166/1204190072048691 https://app.asana.com/0/1203960884932166/1204190072362093 [transitions] Do not remove cpus from configured target graph (#2) Upstream converts ios_multi_cpus to a single value. rules_pods does not. So when rules_pods objc_library rules depend on rules_ios rules, they are considered different configurations, and we end up splitting the configured target graph into two configurations. When swift, objc, etc try to link in all objc_libraries later in the build, they then try to link the same library twice, because the configured nodes are duplicated, and we run into duplicate symbol, module redefinition, etc errors. In theory, this could be reverted once the rules_ios migration is complete, but for our use case, it should not hurt anything being present. This logic, also, only affects our opt builds that build for multiple cpus. The development builds are unaffected. [rules_ios] Re-enable cpp rules (#3) This was accidentally disabled. It is required for glog, so turn this back on so that .cc/.cpp sources and their .a files are properly propagated. Tested by doing a build with this change off of main [rules_ios] Use -idirafter instead of -I (#4) NOTE: that this may cause issues for libraries that anticipate the `-I.` behavior and do something like `#include "Foo.h"` when there are multiple "Foo.h" in libs in its dependencies. In those cases, `-I.` can be added to its copts explicitly. There are some places where using -I can actually cause problems with system header collisions. Notably, fmt has a "locale.h" file. Without this change, you can end up with a chain that is: "fmt/locale.h" -> <locale> -> <clocale> -> <locale.h> -> failure, because -I causes fmt/locale.h to be searched (I believe due to the entries in the headermap being -I) before system paths. See https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html for resolution order [rules_ios] Allow rewriting header paths for frameworks and libraries (#5) This allows us to pick a different relative include path for header files. This is needed because some third party dependencies have e.g. colliding base filenames (folly has multiple Core.h, e.g.), or included files do relative includes (kv-storage includes "kv-storage/api/Core.h"), and with the current approach taken by apple_framework of flattening the headers out, that path doesn't actually exist in the Headers or PrivateHeaders directories of the .framework file. This patch does a few things: - Adds an extra argument "header_mapping". This is how users define where public/private headers should be accessible. If not specified, or a header is not in this mapping, then the basename of the header is used. (e.g. kv-storage.framework/Headers/Core.h) - Updates the hmapbuild binary so that we can specify these destinations in the .hmap files - Updates the umbrella header to use these destinations - Updates apple_framework/apple_library to thread these mappings through. Tested on a WIP branch (annie/native-versions-ios), and we seemed to get past the #include failures, and onto errors in their code itself.

…anup custom patches (#15) This does a few things: - Squashes our existing changes since our last divergence point with main. I only did this because it was easier since we had a lot of iteration on our interim PRs that isn't strictly necessary or relevant anymore. - Removes some patches / patching logic where we had backported functionality from rules_apple. We do not need to patch rules_apple right now. - Rebases us onto upstream version 4.8.2 of rules_ios - Removes apple_common.new_objc_provider in _cc_headers_symlinks_impl. In the new rules_ios, that being present causes it to attempt to infer and build a swift modulemap, which we don't need. - Removes a change we had made to CPU configuration to support both cocoapods and podtobuild at the same time. We're back on the upstream configuration. At the end, the major changes we have vs upstream are: - Adding static_framework rule - Headermap rewriting - Changing some rules from -I to -idirafter - Mark a few things as "system" so we don't see their errors in our builds.

…anup custom patches (#16) Re-applying #15 This does a few things: - Squashes our existing changes since our last divergence point with main. I only did this because it was easier since we had a lot of iteration on our interim PRs that isn't strictly necessary or relevant anymore. - Removes some patches / patching logic where we had backported functionality from rules_apple. We do not need to patch rules_apple right now. - Rebases us onto upstream version 4.8.2 of rules_ios - Removes apple_common.new_objc_provider in _cc_headers_symlinks_impl. In the new rules_ios, that being present causes it to attempt to infer and build a swift modulemap, which we don't need. - Removes a change we had made to CPU configuration to support both cocoapods and podtobuild at the same time. We're back on the upstream configuration. At the end, the major changes we have vs upstream are: - Adding static_framework rule - Headermap rewriting - Changing some rules from -I to -idirafter - Mark a few things as "system" so we don't see their errors in our builds.

Add an
objc_public_headersattribute to apple_* rules. This changes the umbrella header, if set, such that it includes all public_headers headers when compiled against c++, and only a subset of headers (objc_public_headers) when compiled against objective c.The main problem this is solving is that we have a main module map for each library. When trying to import anything from the framework, it loads the entire module map and every include in the umbrella header. If you put c++-only headers in it, it will try to interpret those without c++ support if you try to include the .h from a .m file. This allows us to have headers that mix (obj)c++ and objc in a single framework. It should also allow us to drop some of the -objc rules we've had to clunkily build out.
