45bb461c32 shared_vector require freeze/thaw 
Remove the implicit cast from non-const to const.
Require the use of freeze/thaw when
changing between const and non-const.

Change argument of const_shared_vector_cast
to a non-const shared_vector reference
to allow it to be cleared by freeze/thaw.

74f68c47d3 shared_vector_convert 
Allow converting of shared_vector between types

Conversion utilizes castUnsafe<TO,FROM>().

Converting to/from void is supported.  Convert to void
is an alias for static_shared_vector_cast<void>().
Convert from void utilizes shared_vector<void>::original_type()
and throws std::runtime_error if this is not valid.

Casting now handles 'const void'
is most places where 'void' can be used.

7f9745c8d1 Implement PVStructureArray with shared_vector 
Combine as much as possible with scalar array handling.

PVStructureArray becomes PVValueArray<shared_ptr<PVStructure> >

Bulk of shared implementation moved the PVVectorStorage
which has a parametrized base to avoid using multiple inheritance.

a4cfab1242 Fix "optimize shared_vector for storing non-POD types"

be4738f59c remove weak_vector 
It seems that shared_ptr::use_count() does
not include weak_ptr instances.  Therefore
shared_ptr::use_count()==1 (aka unique())
does *not* ensure exclusive ownership!

This breaks the assumption used by
shared_vector::make_unique() to avoid
allocating a new array in some cases.

bc3187a3f6 optimize shared_vector for storing non-POD types 
pass values by reference where appropriate.
When reallocating arrays of shared_ptr
"move" with swap() instead of operator=
to avoid ref counter inc and dec for each
element.

9e865bc37d Avoid unnecessary copying in copyIn 
Only re-use the existing reference if
it is large enough to hold all the new data.
If it isn't then throw it away to avoid
copying its current contents during
the resize().
