- Partially reverts ed8405d0fd which included
`sgx_dcap_qal.h` in `libsgx-headers` and transferred ownership of its contents
to this repository.
- The QAL API definitions are now transferred back to DCAP, where the QAL implementation
lives.
- The common structure definitions ( `tee_policy_bundle_t`, `tee_policy_auth_result_t`) which
are shared between SGX (TVL) and DCAP repositories are extracted to a new header
`sgx_dcap_qal_types.h` and kept as part of the SGX repository, with the intent
to also be included by DCAP's 'sgx_dcap_qal.h`.
Additional changes:
--------------------
- SGX SDK installer package and `libsgx-headers` DEB/RPM package's BOM changes:
1) *REMOVE* an SGX-side copy of `sgx_dcap_qal.h` (QAL APIs)
This header is still available via `libsgx-dcap-quote-verify-dev` DEB/RPM package,
matching the exported API of the corresponding `libsgx_dcap_quoteverify.so` library.
2) *ADD* `sgx_dcap_qal_types.h` (QAL types, shared with TVL)

SGX SDK–related attestation headers and the TVL sources originating from DCAP
tag: 'DCAP_1.25' are now relocated:
FROM: the intermediate staging area: './external/from_dcap'
(created by the '[from DCAP][move 1/2]...') commit 5b0b8e9)
INTO: their target SGX SDK repository layout.
This is a follow-on commit that places relocated files in its final locations
and updates the build system accordingly.
Additional changes:
--------------------
- `libsgx-headers` DEB/RPM package now also contains the following 2 headers:
1) sgx_qve_header.h
2) sgx_dcap_qal.h
Leveling w/ SDK - both files were part of the SDK already.
- SDK installer package now also contains the `sgx_dcap_constant_val.h` header
(from TVL), including common QvE and QAE identity verification constants.

return SGX_ERROR_FEATURE_NOT_SUPPORTED:
Affected APIs:
* get_launch_token(...)
* sgx_get_whitelist_size(...)

Signed-off-by: Li, Xun <xun.li@intel.com>
Before this commit, the memory access within `do_init_enclave` setting
`g_enclave_state` to `ENCLAVE_INIT_DONE` was entirely unsynchronized.
This could cause the compiler to reorder this access, performing it
earlier than actually written. This would effectively unlock the memory
being initialized for use within other threads before the initialization
is finished.
The issue isn't entirely theoretical, as such an optimization could for
example allow to make one of the calls to `memset_s` a tailcall. The
only thing preventing this is the difficulty of proving that the memset
doesn't alias `g_enclave_state`.
One way to fix this would be to access `g_enclave_state` with C11
atomics of ordering `acq_rel` or stronger. However, the freestanding
environment of the SDK doesn't support C11 atomics. Thus we use the
existing assembly wrappers, which are sufficient as achieving `acq_rel`
semantics in x86 assembly doesn't require any special instructions.
To make it less likely that a similar flaw is reintroduced, we remove
the `extern` declaration of `g_enclave_state` from the header files.
