Improve handling of C compiler intrinsics in translate-c
...
C compiler intrinsics can only appear as part of a function call. When called
they are implicitly cast to a function pointer; treat this as a non-null
pointer so that it emits as a regular Zig function call.
Put `pub usingnamespace @import("std").c.builtins;` at the top of translated
C files so that they will have access to builtin functions defined there.
Fixes #6707

We generally get away with atomic primitives, however a lock is required
around the refresh function since it traverses the Node graph, and we
need to be sure no references to Nodes remain after end() is called.

However, adding a twist where `findFreeSpace` accepts a `SegmentCommand`

that segment and nowhere else.

...
Firstly, we preallocate segments offset and sizes, and then
when adding sections, we find the free space within each segment.
Currently, this applies to any segment that is not __LINKEDIT
segment since this requires special treatment.

std: introduce a thread-local CSPRNG for general use
...
std.crypto.random
* cross platform, even freestanding
* can't fail. on initialization for some systems requires calling
os.getrandom(), in which case there are rare but theoretically
possible errors. The code panics in these cases, however the
application may choose to override the default seed function and then
handle the failure another way.
* thread-safe
* supports the full Random interface
* cryptographically secure
* no syscall required to initialize on Linux (AT_RANDOM)
* calls arc4random on systems that support it
`std.crypto.randomBytes` is removed in favor of `std.crypto.random.bytes`.
I moved some of the Random implementations into their own files in the
interest of organization.
stage2 no longer requires passing a RNG; instead it uses this API.
