Adds a new Version type to pkgbits to represent the version of the
bitstream. Versions let readers and writers know when different data is
expected to be present or not in the bitstream. These different pieces
of data are called Fields, as an analogy with fields of a struct.
Fields can be added, removed or changed in a Version. Extends Encoder
and Decoder to report which version they are.

Adds a -gomodversion flag to testdir. This sets the go version
in generated go.mod files. This is just runindir tests at the moment.
This is a building block so that tests can be written for exported
type parameterized aliases (like reproducing #68526).
This also adds a test that uses this feature. A type parameterized
alias is used so aliastypeparams and gotypesalias must be enabled.
gotypesalias is enabled by the go module version. The alias is not
exported and will not appear in exportdata. The test shows the
package containing the alias can be imported. This encapsulates
the level of support of type parameterized aliases in 1.23.

When deciding which event to store in the M's single available slot,

And, fix a test of sync.Mutex contention that expects those events to

For the moment, Go calls sendfile(2) to transfer at most 4MB at a time
while sendfile(2) actually allows a larger amount of data on one call.
To reduce system calls of sendfile(2) during data copying, we should
specify the number of bytes to copy as large as possible.
This optimization is especially advantageous for bulky file-to-file copies,
it would lead to a performance boost, the magnitude of this performance
increase may not be very exciting, but it can also cut down the CPU overhead
by decreasing the number of system calls.
This is also how we've done in sendfile_windows.go with TransmitFile.
