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.

Implement PT_INTERP, and thus dynamic linking.
...
With this change, gcc can now successfully compile a tiny program that
printfs an integer returned from a function, from a dynamically linked
library that it compiled as well.
Rustc however, is orders of magnitude more complex, and the next step is
to fix constructors which require access to `environ`, in ld.so
