52cfd5ff0a mp_n_root: add mp_n_root_ex() with parameter 'fast' for mp_expt_d_ex() 
This change is introduced to be able to choose the underlying
implementation of mp_expt_d_ex()

The implementation of the root_n functionality is now implemented in the
mp_n_root_ex() function.

The parameter 'fast' is just passed over to mp_expt_d_ex().

mp_n_root() defaults to the pre 921be35779f7d71080ad85c27ed58671602d59b3
implementation

e9b1837c8c mp_expt_d: bring back pre 921be35779f7d71080ad85c27ed58671602d59b3 state 
The implementation of the expt_d functionality is now implemented in the
mp_expt_d_ex() function.

The user can now choose between the old (more timing resistant) version
and the new version by modification of the parameter 'fast'.

mp_expt_d() defaults to the old version

76fe0008a2 Update bn_mp_init_copy.c 
In mp_init_copy(), mp_init() is used to assign the memory with default block size, mp_copy() is used to grow the target mp_int size if it is required and copy the content.

My suggestion is to use mp_init_size() instead of mp_init() inside the mp_init_copy to assign required memory depending on the source mp_int size and then use mp_copy to copy the content. This will avoid the subsequent mp_grow() inside the mp_copy(). 

The associated issue number is 11 in GitHub.
