cmd/cgo: use C exact-width integer types to represent Go types The exact-width integer types are required to use two’s complement representation and may not have padding bits, cf. §7.20.1.1/1 in the C11 standard or https://en.cppreference.com/w/c/types/integer. This ensures that they have the same domain and representation as the corresponding Go types.

all: gofmt more (but vendor, testdata, and top-level test directories) CL 294430 made packages in std and cmd modules use Go 1.17 gofmt format, adding //go:build lines. This change applies the same formatting to some more packages that 'go fmt' missed (e.g., syscall/js, runtime/msan), and everything else that is easy and safe to modify in bulk. Consider the top-level test directory, testdata, and vendor directories out of scope, since there are many files that don't follow strict gofmt formatting, often for intentional and legitimate reasons (testing gofmt itself, invalid Go programs that shouldn't crash the compiler, etc.). That makes it easy and safe to gofmt -w the .go files that are found with gofmt -l with aforementioned directories filtered out: $ gofmt -l . 2>/dev/null \| \ grep -v '^test/' \| \ grep -v '/testdata/' \| \ grep -v '/vendor/' \| wc -l 51 None of the 51 files are generated. After this change, the same command prints 0. For #41184.

misc/cgo/test: consolidate tests into fewer cgo source files Each different file that does import "C" must be compiled and analyzed separately by cgo. Having fewer files import "C" reduces the cost of building the test. This is especially important because this test is built and run four different times (with different settings) during all.bash. go test -c in this directory used to take over 20 seconds on my laptop. Now it takes under 5 seconds. Removes 23.4r 29.0u 21.5s from all.bash. For #26473.
