/** Skip past an INTEGER in an ASN.1 buffer.

*
|
|
* Mark the current test case as failed in any of the following conditions:
|
|
* - The buffer does not start with an ASN.1 INTEGER.
|
|
* - The integer's size or parity does not match the constraints expressed
|
|
* through \p min_bits, \p max_bits and \p must_be_odd.
|
|
*
|
|
* \param p Upon entry, `*p` points to the first byte of the
|
|
* buffer to parse.
|
|
* On successful return, `*p` points to the first byte
|
|
* after the parsed INTEGER.
|
|
* On failure, `*p` is unspecified.
|
|
* \param end The end of the ASN.1 buffer.
|
|
* \param min_bits Fail the test case if the integer does not have at
|
|
* least this many significant bits.
|
|
* \param max_bits Fail the test case if the integer has more than
|
|
* this many significant bits.
|
|
* \param must_be_odd Fail the test case if the integer is even.
|
|
*
|
|
* \return \c 0 if the test failed, otherwise 1.
