4f1a54e41d84a81e4506668bfabed1f3c632973b Move valgrind CPPFLAGS into SECP_CONFIG_DEFINES (Pieter Wuille)
Pull request description:
This introduces an abstraction layer `src/checkmem.h`, which defines macros for interacting with memory checking tools. Depending on the environment, they're mapped to MemorySanitizer builtins, Valgrind integration macros, or nothing at all.
This means that msan builds immediately benefit from existing undefined memory checks in the tests. It also means those builds result in a `ctime_tests` (new name for `valgrind_ctime_test`) binary that can usefully test constant-timeness (not inside Valgrind, and with the downside that it's not running against a production library build, but it's faster and available on more platforms).
Such an msan-ctime test is added to the Linux x86_64 msan CI job, as an example. More CI cases could be added (e.g. for MacOs or ARM Linux) later.

e862c4af0c5a7300129700d38eff499a836a108d Makefile: add -I$(top_srcdir)/src to CPPFLAGS for precomputed (Matt Whitlock)
Pull request description:
When performing an out-of-source-tree build, regenerating the source files for the precomputed ecmult tables places them outside the source tree. Then, when they are to be compiled, they cannot find the headers they need because the source tree is absent from their include search path. This appears to have been an oversight, as the relevant `-I` options are present in `libsecp256k1_la_CPPFLAGS` but were missing from `libsecp256k1_precomputed_la_CPPFLAGS`. This PR adds them.

Pull request description:
This is an improved version of some of the tidying/refactoring in #1170.
I think it's enough to deserve a separate PR. Once this is merged, I'll get back to the actual goal of #1170 (namely, forbidding cloning and randomizing static contexts.)
This PR is a general clean up of the context tests. A notable change is that this avoids a code smell where `run_context_tests()` would use the global `ctx` variable like a local one (i.e., create a context in it and destroy it afterwards). After this PR, the global `ctx` is properly initialized for all the other tests, and they can decide whether they want to use it or not. Same for a global `sttc`, which is a memcpy of the static context (we need a writable copy in order to be able to set callbacks).
Note that this touches code which is also affected by #1167 but I refrained from trying to solve this issue. The goal of this PR is simply not to worsen the situation w.r.t. #1167. We should really introduce a macro to solve #1167 but that's another PR.

Pull request description:
I wanted to experiment with what would be required to split up `secp256k1_i128_to_i64` between those cases when a signed 64 bit value is being demoted, versus an unsigned 64 bit value is being extracted from the lower bits, and this is the result.
I'm not sure this is a useful PR, so feel free to close it. However, since it is already written, I figured it is worth at least discussing.

This change eases the use of alternate build systems by moving
the variables in `src/libsecp256k1-config.h` to compiler macros
for each invocation, preventing duplication of these variables
for each build system.
