The limit is 500. There is no way to change it.
This primarily affects name resolution.
If a million goroutines try to resolve DNS names,
only 500 will get to execute cgo calls at a time.
But in return the operating system will not crash.
Fixes#5625.

Actually working to stay within the limit could cause subtle deadlocks.
Crashing avoids the subtlety.

When the new call site-specific frame bitmaps are available,
we can cut the zeroing to just those values that need it due
to scope escaping.

When identifying structs or interfaces we really want to know
their makeup, not just their name.

Jumps to the same file will use the original buffer, not the
coverage buffer. Making it work for the coverage buffer isn't
worth the trouble, especially because it would break as soon as
you jump to a different file and back.
Use error instead of message so it actually terminates

When the packages the tested package depends on don't build,
we weren't getting out early. Added a simple check for a successful
build to an existing early out.
There may be other ways that double compilation arises, but
this fixes the one listed in the issue.

The goal is to stop only those programs that would keep
going and run the machine out of memory, but before they do that.
1 GB on 64-bit, 250 MB on 32-bit.
That seems implausibly large, and it can be adjusted.

Rows.Close.
Previously, callers that followed the example code (but not call
rows.Close after "for rows.Next() { ... }") could leak statements if
the driver returned an error other than io.EOF.

This CL is about getting all the right checks inserted.
A followup CL will add an optimization pass to
remove redundant checks.

This CL rearranges the call order for raw networking primitives like
the following;
- For dialers that open active connections, pollDesc.Init will be
called before syscall.Connect.
- For stream listeners that open passive stream connections,
pollDesc.Init will be called just after syscall.Listen.
- For datagram listeners that open datagram connections,
pollDesc.Init will be called just after syscall.Bind.
This is in preparation for runtime-integrated network pollster for BSD
variants.
