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.

Follows up on 590856d (removing the Linux LE).
Removes all of whitelist management and LE facilities from the AESM and SDK.
Leaves only skeleton API stubs behind (for partial ABI compatibility).
!BREAKING CHANGES!
- Launch-related stub(`libsgx_launch.so`) and simulation (`libsgx_launch_sim.so`) libraries
removed from the SGX SDK.
- Removed AESM support for the deprecated Linux SGX out-of-tree (OOT) driver
(will no longer attempt an enclave load if OOT driver is detected)
- AESM APIs for launch control and whitelist management will now
return SGX_ERROR_FEATURE_NOT_SUPPORTED:
Affected APIs:
* get_launch_token(...)
* sgx_get_whitelist_size(...)
* sgx_get_whitelist(...)
* sgx_register_wl_cert_chain(...)
- Deprecated `sgx_uae_launch.h` SDK header
- Marked init token inputs `reserved` in the relevant loader APIs (no longer in use)

Update SGX quote-related headers and simulation code to align with DCAP/ECDSA quote v3.
Replace `sgx_quote_t` sizing/usage with `sgx_quote3_t` in internal and simulator paths, add `SGX_DEPRECATED_MSG` for message-bearing deprecation annotations in legacy EPID/PSE types, fix `#pragma pack(pop)` in `pce_cert.h`, and extend simulator build includes to pick up DCAP QuoteGeneration headers.

Currently we seed random number generator with timestamp in seconds.
Because of this we have to insert 1 second delay in each testcase to
ensure the randomness, which prevents us from testing applications
effeciently.
Simulation mode is not supposed to be used in production, but
developing applications on environtment without SGX HW is still common.
So let's seed with timestamp in nanoseconds in simulation mode.

The load_regs assembly function uses its caller's frame pointer.
C/C++ compilers are allowed to make optimizations to their
representation of the stack, and frequently omit the frame pointer.
The functions _EEXIT in t_instructions.cpp and _SE3 in
u_instructions.cpp both call load_regs, and thus should be the only ones
that should be affected by deoptimization.
Even -O0 may omit the frame pointer (indeed we found this to be the case
when compiling with GCC 7.3.0), so this change also makes that requirement
explicit by by means of -fno-omit-frame-pointer.
The analogous attribute for -fno-omit-frame-pointer is not available in
clang, so the clang version of the LOAD_REGS_ATTRIBUTES is simply
[[clang:optnone]].
An added bonus of switching the -O0 flag over to an attribute in source
code is that alternate build tools are easier to port to :)
