Jim Mussared b6a9778484 py/misc: Change sizeof to offsetof for variable-length alloc.
This fixes the case where e.g.

    struct foo_t {
      mp_obj_t x;
      uint16_t y;
      char buf[];
    };

will have `sizeof(struct foo_t)==8`, but `offsetof(struct foo_t, buf)==6`.

When computing the size to allocate for `m_new_obj_var` we need to use
offsetof to avoid over-allocating. This is important especially when it
might cause it to spill over into another GC block.

Jim Mussared 45ac651d1a all: Rename *umodule*.c to remove the "u" prefix.
Updates any includes, and references from Makefiles/CMake.

This essentially reverts what was done long ago in commit
