0ecf318851 ci: Use remote pull/merge ref instead of local git merge
The merge strategy on the remote may be different than the local one.
This may cause local merges to be different or fail completely. Fix this
by using the result of the remote merge.

c2e0fdadebd2f9bf06fd73b9e89dae03133d71f9 ci: set -u in cirrus.sh to treat unset variables as an error (Jonas Nick)

Pull request description:

  This PR is supposed to prevent accidental misuse of cirrus.sh. Maybe there is a way to check if `CC`, `AR` and `NM` are set within the loop that deals with the other variables, but so far I did not come up with one (that's POSIX shell compliant).

Merge bitcoin-core/secp256k1#1000: Synthetic int128 type.

2914bccbc0913806ee64425a27d38cdc27b288e8 Simulated int128 type. (Russell O'Connor)

Pull request description:

  Abstracts the int128 type and provides an native version, if available, or a implements it using a pair of int64_t's.

  This is activated by setting the configuration flag `--with-test-override-wide-multiply=int128_struct`.

  The primary purpose of this PR is to take advantage of MSVC's [umulh](https://docs.microsoft.com/en-us/cpp/intrinsics/umulh?view=msvc-170) intrinsic that we can use to simulate an int128 type which MSVC does not have (AFAIU). This PR lays out the groundwork for this level of MSVC support, but doesn't include the configuration logic to enable it yet.

  For completeness, and implementation of `umulh` and `mulh` are also provided for compilers that support neither the intrinsic nor the int128 type (such as CompCert?).  This also opens up the possibility of removing the 32-bit field and scalar implementations should that ever be desired.
