handle serial buffer overflow condition (while the modem protocol *can* send frames >512 bytes the serial port handler can only handle frames up to 512 bytes); better handle transmitting double length (512 byte) P25 PDU frames;

P25 data ( #4 )
...
* rework modem protocol to support variable length frames up to 64k; refactor P25 PDU handling to support TIA-102 minimum 512 byte frames;
* ensure length accounts for frame header;
* fix support for incoming long frames;

treewide: perform general refactor of file headers, I've modified the file headers to follow rules from: https://www.kernel.org/doc/html/next/process/license-rules.html , this trims/compresses the file header section a bit reducing the number of lines at the top of every file quite a bit, going forward all new files should follow this new format (if its good enough for the Linux kernel, its good enough for me);

correct edge case situation where discriminator or post bandwidth may be set when they shouldn't be; cleanup bad references to the ADF7021's REG13 reference (the old code worked fine, but used magic numbers instead of proper named defines); add more verbose register debug output from the modem; display NXDN sync values copied to the bit buffer and not the sync bytes;
