8af59d1f98 ComptimeStringMap: return a regular struct and optimize
this patch renames ComptimeStringMap to StaticStringMap, makes it
accept only a single type parameter, and return a known struct type
instead of an anonymous struct.  initial motivation for these changes
was to reduce the 'very long type names' issue described here
https://github.com/ziglang/zig/pull/19682.

this breaks the previous API.  users will now need to write:
`const map = std.StaticStringMap(T).initComptime(kvs_list);`

* move `kvs_list` param from type param to an `initComptime()` param
* new public methods
  * `keys()`, `values()` helpers
  * `init(allocator)`, `deinit(allocator)` for runtime data
  * `getLongestPrefix(str)`, `getLongestPrefixIndex(str)` - i'm not sure
     these belong but have left in for now incase they are deemed useful
* performance notes:
  * i posted some benchmarking results here:
    https://github.com/travisstaloch/comptime-string-map-revised/issues/1
  * i noticed a speedup reducing the size of the struct from 48 to 32
    bytes and thus use u32s instead of usize for all length fields
  * i noticed speedup storing KVs as a struct of arrays
  * latest benchmark shows these wall_time improvements for
    debug/safe/small/fast builds: -6.6% / -10.2% / -19.1% / -8.9%. full
    output in link above.

4c393c7468 Update usages of fmtId/isValidId
`{}` for decls
`{p}` for enum fields
`{p_}` for struct fields and in contexts following a `.`

Elsewhere, `{p}` was used since it's equivalent to the old behavior.

fd2239bde9 child_process + Build: rename exec to run + all related code
Justification: exec, execv etc are unix concepts and portable version
should be called differently.

Do no touch non-Zig code. Adjust error names as well, if associated.
Closes #5853.

11fcbe5a46 gen_linux_syscalls: use default max output bytes
Apparently, 20KiB is not enough anymore.

815e53b147 Update all std.mem.tokenize calls to their appropriate function
Everywhere that can now use `tokenizeScalar` should get a nice little performance boost.

a4369918b1 Generate linux syscalls via. the linux source tree
Previously, updating the `SYS` enum for each architecture required
manually looking at the syscall tables and inserting any new additions.

This commit adds a tool, `generate_linux_syscalls.zig`, that automates
this process using the syscall tables in the Linux source tree. On
architectures without a table, it runs `zig cc` as a pre-processor to
extract the system-call numbers from the Linux headers.
