* agent/tpm2.c: New. * agent/Makefile.am (gpg_agent_SOURCES): Add new file. (gpg_agent_LDFLAGS): Add DL_LIBS. * agent/tpm2.h: New. -- This commit adds code to handle the three specific functions needed to make the agent TPM aware, namely the ability to load a key from shadow information, the ability to sign a digest with that key, the ability to decrypt with the key and the ability to import a key to the TPM. The TPM2 is a bit of an esoteric beast, so all TPM specific callouts are confined inside this code. Additionaly, it requires the tss2 library to function, so the code is designed such that if the library isn't present then all TPM functions simply fail. This allows the code to be compiled with TPM support, but not require that the support library be present on the system.
