Windows: Registry based configuration

Load configuration data in the registry into a krb5_config_section.
Each registry key corresponds to a krb5_config_section and each
registry value becomes a bound string value.

The set of values contained in the root Heimdal registry key is
treated as if they were defined in the [libdefaults] section.

E.g. the configuration file:

[libdefaults]
foo = bar

[Foo]
x = y
y = {
  baz = quux
}

is equivalent to the registry keys:

[HKEY_CURRENT_USER\Software\Heimdal]
"foo"="bar"

[HKEY_CURRENT_USER\Software\Heimdal\Foo]
"x"="y"

[HKEY_CURRENT_USER\Software\Heimdal\Foo\y]
"baz"="quux"
