Migrate Coroutine_test and JobQueue_test from Boost.Coroutine to
C++20 std::coroutine using CoroTask/CoroTaskRunner:
- Coroutine_test: Replace Coro-based coroutine tests with CoroTask
equivalents using co_await runner->yieldAndPost().
- JobQueue_test: Replace Coro suspend/resume patterns with CoroTask
equivalents, use pointer-by-value captures in coroutine lambdas
to avoid dangling reference issues.
Migrate all production coroutine entry points from Boost.Coroutine
to C++20 std::coroutine using the CoroTask/CoroTaskRunner primitives:
- RipplePathFind: Replace Coro suspend/resume with co_await pattern,
add cv timeout for graceful shutdown.
- ServerHandler: Replace Coro-based processRequest with CoroTask,
simplify coroutine lifecycle management.
- GRPCServer: Replace Coro with CoroTask for streaming RPC handlers.
- Remove Coro usage from Context.h aggregate initialization.
- Add exception handling in coroutine bodies to prevent unhandled
exceptions from escaping the coroutine frame.
Add C++20 std::coroutine based task primitives for the JobQueue:
- CoroTask<T>: A coroutine return type with RAII ownership semantics
and symmetric transfer for efficient resumption.
- CoroTaskRunner: Manages coroutine lifecycle on the JobQueue with
suspend/resume tracking, LocalValue preservation, and graceful
shutdown support.
- JobQueueAwaiter: External awaiter combining yield+post atomically.
- yieldAndPost(): Inline awaiter workaround for GCC-12 codegen bug
where external awaiters at multiple co_await points corrupt the
coroutine state machine resume index.
- CoroTask_test: Comprehensive test suite covering task lifecycle,
suspend/resume, shutdown, and value-returning coroutines.
- BoostToStdCoroutineSwitchPlan.md: Migration plan documentation.
Comprehensive migration plan documenting the switch from
Boost.Coroutine2 to C++20 standard coroutines in rippled, including
research analysis, implementation phases, risk assessment, and
testing strategy.

This change:
* Removes a set of unnecessary brackets in the initialization of an `std::uint32_t`.
* Fixes a couple of incorrect flags (same value, just wrong variables - so no amendment needed).
This change replaces all instances of `<variable> != tesSUCCESS` with `!isTesSuccess(<variable>)` and `<variable> == tesSUCCESS` with `isTesSuccess(<variable>)`.
This change fixes delegation:
* If the Delegate object is not present, we should disallow empty permission list in DelegateSet preclaim.
* Empty permission list is only allowed to delete the existing Delegate object.
* In `doApply`, permission list being empty returns `tecINTERNAL`, which should not happen.
This change:
* Makes `addSLE` in `DIDSet` a static function, instead of a free function.
* Renames `Attestation` to `Data` everywhere (an artifact of a previous name for the field).
* Actually runs a set of tests that were not included in the `run` function of `DID_test`.
This change:
* Introduces a new helper function on `STTx`, `getFeePayer`.
* Removes the usage of `mSourceBalance` and replaces it with SLE balance lookups.
* Renames `mPriorBalance` to `preFeeBalance_`
This simplifies some of the code in the transactors and makes it a lot more readable.
Throwing exceptions from code sometime confuses ASAN, as it cannot keep track of stack frames. This change therefore adds a macro to skip instrumentation around the `Throw` function.
This change moves the sanitizer runtime options out to dedicated files, such that they can be used in multiple places (CI, local runs) without any need to rewrite them.
Per [XLS-0095](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html), we are taking steps to rename ripple(d) to xrpl(d). This change modifies the system name from `rippled` to `xrpld`.
The system name is used in limited places:
* When no explicit config file is passed via the `--config` flag, then the system name is used to construct the path where the config file and database may be stored, via the `$XDG_CONFIG_HOME` and `$XDG_DATA_HOME` directories, respectively.
* It is used in the metadata and user-agent as part of RPC calls.
* It is newly used in the full version string.
