Likewise, cleanup some minor whitespace issues around comments.
The implementation from crypto/sha256 is also shared with notsha256.
It is copied, but preserves notsha256's go:build directives. They are

workarounds to support XXLOR on older toolchains. This is not needed
anymore as the minimum bootstrap (1.17) compiler will support XXLOR.

Fix the coversion between our sentinel salt length variables and the
BoringSSL versions in SignRSAPSS. We previously set -1 (hash length
equals salt length) when 0 was passed when we should've been setting
-2. This now matches the conversion that happens in VerifyRSAPSS. Also
adds a note documenting why we do this.
Additionally in non-Boring mode, properly handle passing of salt lengths
with a negative value which aren't one of the magic constants, returning
an error instead of panicking.

As it can't appear in user package paths.
There is a hack for handling "go:buildid" and "type:*" on windows/386.
Previously, windows/386 requires underscore prefix on external symbols,
but that's only applied for SHOSTOBJ/SUNDEFEXT or cgo export symbols.
"go.buildid" is STEXT, "type.*" is STYPE, thus they are not prefixed
with underscore.
In external linking mode, the external linker can't resolve them as
external symbols. But we are lucky that they have "." in their name,
so the external linker see them as Forwarder RVA exports. See:
- https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#export-address-table
- https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/pe-dll.c;h=e7b82ba6ffadf74dc1b9ee71dc13d48336941e51;hb=HEAD#l972)
This CL changes "." to ":" in symbols name, so theses symbols can not be
found by external linker anymore. So a hacky way is adding the
underscore prefix for these 2 symbols. I don't have enough knowledge to
verify whether adding the underscore for all STEXT/STYPE symbols are
fine, even if it could be, that would be done in future CL.
