Introduce TlsAuthConfigLib to read the list of trusted CA certificates
from fw_cfg and to store it to EFI_TLS_CA_CERTIFICATE_VARIABLE.
The fw_cfg file is formatted by the "p11-kit" and "update-ca-trust"
utilities on the host side, so that the host settings take effect in guest
HTTPS boot as well. QEMU forwards the file intact to the firmware. The
contents are sanity-checked by NetworkPkg/HttpDxe code that was added in
commit 0fd13678a6.
Link TlsAuthConfigLib via NULL resolution into TlsAuthConfigDxe. This sets
EFI_TLS_CA_CERTIFICATE_VARIABLE in time for both
NetworkPkg/TlsAuthConfigDxe (for possible HII interaction with the user)
and for NetworkPkg/HttpDxe (for the effective TLS configuration).
The file formatted by "p11-kit" can be large. On a RHEL-7 host, the the
Mozilla CA root certificate bundle -- installed with the "ca-certificates"
package -- is processed into a 182KB file. Thus, create
EFI_TLS_CA_CERTIFICATE_VARIABLE as a volatile & boot-time only variable.
Also, in TLS_ENABLE builds, set the cumulative limit for volatile
variables (PcdVariableStoreSize) to 512KB, and the individual limit for
the same (PcdMaxVolatileVariableSize) to 256KB.
