* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.
This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.
Updates #1472
PiperOrigin-RevId: 289033387
This allows writable proc and devices files to be opened with O_CREAT|O_TRUNC.
This is encountered most frequently when interacting with proc or devices files
via the command line.
e.g. $ echo 8192 1048576 4194304 > /proc/sys/net/ipv4/tcp_rmem
Also adds a test to test the behavior of open(O_TRUNC), truncate, and ftruncate
on named pipes.
Fixes#1116
PiperOrigin-RevId: 282677425
This does not actually implement an efficient splice or sendfile. Rather, it
adds a generic plumbing to the file internals so that this can be added. All
file implementations use the stub fileutil.NoSplice implementation, which
causes sendfile and splice to fall back to an internal copy.
A basic splice system call interface is added, along with a test.

This change will add support for /proc/sys/net and /proc/net which will
be managed and owned by rpcinet. This will allow these inodes to be forward
as rpcs.
