Implement and use locale-independent strtod function

It is called strtod_c and internally uses strtod_l on OSX and Linux.
On Windows a function derived from the python source code is used
that replaces the decimal delimiter by the locale one and calls the
standard strtod function.

fix #5344
Add unexported get! macro for Dicts

Same as get! function but does not evaluate the default
argument unless needed.
Faster cache lookup in broadcast! via get! macro

Change broadcast! cache to use nested Dict instead of a Dict with Tuple
keys; use get! macro to access its fields.
Related to #6041.

Also reduces code duplication in broadcast! definitions via eval macro.
Add a note of caution to get! macro
