gpg_sign: add local ipk package signing functionality
Implement ipk signing inside the sign_ipk bbclass using the gpg_sign module and configure signing similar to how rpm does it. sign_ipk uses gpg_sign's detach_sign because its functionality is identical to package feed signing. IPK signing process is a bit different from rpm: - Signatures are stored outside ipk files; opkg connects to a feed server and downloads them to verify a package. - Signatures are of two types (both supported by opkg): binary or ascii armoured. By default we sign using ascii armoured. - Public keys are stored on targets to verify ipks using the opkg-keyrings recipe.

1# Class for generating signed IPK packages.
2#
3# Configuration variables used by this class:
4# IPK_GPG_PASSPHRASE_FILE
5# Path to a file containing the passphrase of the signing key.
6# IPK_GPG_NAME
7# Name of the key to sign with.
8# IPK_GPG_BACKEND
9# Optional variable for specifying the backend to use for signing.
10# Currently the only available option is 'local', i.e. local signing
11# on the build host.
12# IPK_GPG_SIGNATURE_TYPE
13# Optional variable for specifying the type of gpg signatures, can be:
14# 1. Ascii armored (ASC), default if not set
15# 2. Binary (BIN)
16# GPG_BIN
17# Optional variable for specifying the gpg binary/wrapper to use for
18# signing.
19# GPG_PATH
20# Optional variable for specifying the gnupg "home" directory:
