In Go 1.15, if a dependency is required but not listed in go.mod/go.sum,
it's resolved and added automatically.
This is changing in 1.16. From that release, one will have to explicitly
update the mod files via 'go mod tidy' or 'go get'.
To get ahead of the curve, start using -mod=readonly to get the same
behavior in 1.15, and fix all existing tests.
The only tests that failed were imports.txt and syntax.txt, the only
ones to require other modules. But since we're here, let's add the 'go'
line to all go.mod files as well.
That is, a package that is built without obfuscation imports an
obfuscated package. This will result in confusing compilation error
messages, because the importer can't find the exported names from the
imported package by their non-obfuscated names:
> ! garble build ./importer
[stderr]
# test/main/importer
importer/importer.go:5:9: undefined: imported.Name
exit status 2
Instead, detect this bad input case and provide a nice error:
public package "test/main/importer" can't depend on obfuscated package "test/main/imported" (matched via GOPRIVATE="test/main/imported")
For now, this is by design. It also makes little sense for a public
package to import an obfuscated package in general, because the public
package would have to leak details about the private package's API and
behavior.
While at it, fix a quirk where we thought the unsafe package could be
private. It can't be, because the runtime package is always public and
it imports the runtime package:
public package "internal/bytealg" can't depend on obfuscated package "unsafe" (matched via GOPRIVATE="*")
Instead of trying to obfuscate "unsafe" and doing nothing, simply add it
to the neverPrivate list, which is also a better name than
"privateBlacklist" (for #169).
Fixes#164.

This is important, because it would mean that we would obfuscate
nothing. At best, it would be confusing; at worst, it could mislead
the user into thinking the binary is obfuscated.
Fixes#20.
Updates #108.
