Default ports trees are initialized during
`ndpi_finalize_initialization()`
Make `ndpi_init_detection_module()` less likely to fail, because there
are less memory allocations.
The hard limit of total number of protocols (internal and custom) is ~65535,
because protocol ids are `u_int16_t`...
API changes:
1. From `NDPI_MAX_SUPPORTED_PROTOCOLS + NDPI_MAX_NUM_CUSTOM_PROTOCOLS` to
`ndpi_get_num_protocols()` (after having called
`ndpi_finalize_initialization()`);
2. From `proto_id >= NDPI_MAX_SUPPORTED_PROTOCOLS` to
`ndpi_is_custom_protocol(proto_id)` (after having called
`ndpi_finalize_initialization()`);

Partial revert of 88bfe2cf0: in the trees we save the index and no more
a pointer to `ndpi_struct->proto_defaults[]`.
Remove same functions from public API
