Make the following enhancements to NSS's ASN.1 printing code:
- Print warning messages that are properly indendented.
- PrintAsHex notices when the buffer contains entirely printable characters, and is larger than an int, and prints it as text in that case.
- PrintRawString now indents the string, rather than always printing it on
a separate line.
- now prints decoded bit strings
- now prints BMP (UCS2) strings as strings (not as hex) when they contain only printable ASCII characters.
- now prints Universal (UCS4) Strings as strings (not hex) when they contain only printable ASCII characters.
- Decodes certain encoded data that was previously printed as hex.
- Generically decodes ASN.1 data, rather than merely printing an error, when the ASN.1 data doesn't fit a known template.
- properly handles all optional components of basic constraints extensions.
- Prints the names of the bits in the X509 Key Usage extension.
- Prints General Names.
- Print Auth Key ID extensions
- Print subject and issuer alt name extensions
- Print CRL distribution points extensions
- format and print name constraints extensions
- print Authority Information Access extensions
- Print optional X509v2 subject and issuer Unique ID bit strings
