From RFC 1952:
> If FHCRC is set, a CRC16 for the gzip header is present,
> immediately before the compressed data. The CRC16 consists
> of the two least significant bytes of the CRC32 for all
> bytes of the gzip header up to and not including the CRC16.
* no longer repeat -lc on the linker line redundantly
* when using linkLibrary() with a static library, it will now also put
the static library's static library dependencies on the linker line,
recursively.
* refactor out a common pattern to an addFlag function
I was testing this with wazero, which defaults to not propagate any env
variables. This ensures we don't try to allocate zero length buffers
when there are no results from either function.

We do not need more for the purpose of parsing and synthesising
unwind info by the linker. If we ever decide to generate unwind
info for Zig by the compiler, we can re-add packed struct defs
again.
After this change, the system will be inspected for root certificates
only upon the first https request that actually occurs. This makes the
compiler no longer do SSL certificate scanning when running `zig build`
if no network requests are made.
I originally started monkeying with this because std.mem.zeroes doesn't support sentinel-terminated const slices even with defaults in 0.10.x.
I see that std.mem.zeroes was modified in #13256 to allow setting these slices to "".
That got me partway to where I wanted, but there was still an issue fields whose types are structs, they wouldn't get their defaults.
So when iterating struct fields looking for default values, when there is no default value and the type is .Struct, it will delegate to a call to zeroInit.
* Initialize struct fields in zeroInit exactly once
In my changes, similar to the previous implementation, the priority order for fields being initialized is:
1. If the `init` argument is a tuple, the nth element corresponding to the nth field of the struct.
2. Otherwise, if the `init` argument is not a tuple, try to find a matching field name on `init` and use that field.
3. Is the field has a default value, initalize with that value.
4. Fall back to what the field would have been initialized to via a recursive call to `std.mem.zeroInit`.
But instead of initializing a default instance of the struct and then running multiple passes over it, the init method is chosen per-field and each field is initialized exactly once.
* Changed the interface to align with the new allocator interface.
* Fixed bug where not enough memory was allocated for the header or to
align the pointer.
