fix(linker): deref uninit TCB
...
The bug is described for `x86_64` and Linux but is the same for other architectures and on Redox.
`Tcb::current()` is used to retrieve the current TCB, which is done by by reading `fs:[0x10]`. The TCB layout describes that at offset `0x10`, there is `tcb_ptr: *mut GenericTcb<...>`, which is nothing more but a pointer to itself.
This is fine as otherwise a system call would be required to get the TCB (`arch_prctl(ARCH_GET_FS)` on Linux).
However, this is problematic as the function may be called when the FS base is not set, and in that case the expected output of the function should be [`None`], but we don't currently handle that.
To fix this, any code paths that maybe call this function on an uninitialized TCB are be switched to call `current_slow()`. Which just uses `arch_prctl(ARCH_GET_FS)` to get the FS base and check if it's non-zero.

Exit should return never (!)
...
`_Exit`, `exit`, and related functions should return `!` because they
don't return. This also signals to cbindgen that it should emit
`[[noreturn]]` for those functions.

Avoid over allocations & reallocations
...
As we know, vectors amortize the cost of adding new elements by reserving
space for multiple elements when full. This is useful but may lead to
allocating more memory than necessary.
`relibc` generally avoids over allocations by reserving the exact amount
of space when possible. I fixed a few areas that still over allocated or
reallocated unnecessarily by leveraging iterators that are more likely
to know sizes.
