Enable the API compatibility layer that supports wraps the new API in old API.
Its use is meant only for easing transistion to the new API and will remain exactly
one release. It is scheduled to be removed in version 2.1.

According to EN 300 468, 12 bits after the frequency field are reserved
for future use. Thus, they should be set to 1.

The generation function for the subtitling descriptor erroneously uses the
modulo operation instead of a bitwise AND.

scaled by 8 instead of by 5.

Due to scaling the index variable by 8 instead of 4, the generation function of
the parental rating descriptor makes out-of-bounds array accesses.

The decoding function for the CA identifier descriptor does not take into
account the lower byte of i_ca_system_id.

Since one NVOD reference structure takes 6 bytes, the number of all structures
contained in the descriptor should be the length of its payload divided by 6,
not the remainder of this division.

Due to the lack of parenthesis, the expression used to read handover_type was
read as (p_descriptor->p_data[7] & (0xF0 >> 4)).

Linkage descriptor's generation and decoding routines improperly calculated the
beginning of the private data region in cases where linkage_type = 8,
handover_info = 0, and origin_type = 1.

The shortest valid linkage descriptor contains 56 bits = 7 bytes of payload.
Since the maximum possible payload length is 253 bytes, this leaves 246 bytes
for private data, not 248.

Also, the length checks were changed in order to check the minimum possible
length of the descriptor with the given data, instead of checking maximum
lengths.
