This moves .rc/.manifest compilation out of the main Zig binary, contributing towards #19063
Also:
- Make resinator use Aro as its preprocessor instead of clang
- Sync resinator with upstream
Use inline to vastly simplify the exposed API. This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.
The INCLUDE variable being used during `.rc` preprocessing was an accidental regression in https://github.com/ziglang/zig/pull/17412.
Closes#17585.
resinator changes:
source_mapping: Protect against NUL bytes in #line filenames
lex: Avoid recalculating column on every tab stop within string literals
Proper error handling for failing to open cwd instead of `catch unreachable`
Use platform-specific delimiter for INCLUDE env var parsing
Introduce introspect.EnvVar which tracks all the environment variables
that are observed by the compiler, so that we can print them with `zig
env`.
The `zig env` command now prints both the resolved values as well as all
the possibly observed environment variables.
