Put everything into namespace cln. All fundamental data types still

carry their old names. Other non-macro identifiers are now written as

cln::foo instead of cl_foo, except where the cl_ comes from a data type

(as in cl_I_to_int()). Headers are installed into a separate

C integers.

`type::type (const long)' and `type::type (const unsigned long)'
|
| 528 |
|
|
for type=cl_number, type=cl_N, type=cl_RA, type=cl_I that most often

caused a core dump.
