This CL is a copy of CL 106275 (see CL 106275 for details).
It introduces CertInfo, CertTrustListInfo and CertRevocationCrlInfo
types. It uses pointers to new types instead of uintptr in CertContext,
CertSimpleChain and CertRevocationInfo.
CertRevocationInfo, CertChainPolicyPara and CertChainPolicyStatus types
have uintptr field that can be pointer to many different things
(according to Windows API). So this CL introduces Pointer type to be
used for those cases.

On some builders TestStatx occassionally fails when comparing atime
between Statx and Stat/Lstat.
--- FAIL: TestStatx (0.00s)
syscall_linux_test.go:365: Statx: returned stat atime does not match Lstat
Fix it by dropping the atime comparison, it's enough to verify Statx
working correctly by comparing ctime and mtime. Also, not all
filesystems support atime.

The mkfifo syscall is disallowed on android and iOS. sched_setaffinity
is disallowed on android. Skip all tests which use them.
/usr/bin does not exist on android. Use /system/bin in TestGetwd
instead, like TestChdirAndGetwd in the os package.
Like linux, android does not support Fchmodat with flags != 0. Adjust
TestFchmodat accordingly.
TestDevices might stat some device files which are not accessible, skip
those.
iOS cannot exec subprocesses, thus skip TestPassFD.

It's only when dest is set to NULL that the OS X implementations of
getxattr() and listxattr() return the current sizes of the named
attributes. An empty byte array is not sufficient. To maintain the same
behaviour as the linux implementation, we wrap around the system calls
and pass in NULL when dest is empty.
The parameters for the OS X implementation of setxattr() vary slightly
compared to the linux system call, specifically the 'position'
parameter:
linux:
int setxattr(
const char *path,
const char *name,
const void *value,
size_t size,
int flags
);
darwin:
int setxattr(
const char *path,
const char *name,
void *value,
size_t size,
u_int32_t position,
int options
);
'position' specifies the offset within the extended attribute. In the
current implementation, only the resource fork extended attribute makes
use of this argument. For all others, position is reserved. We simply
default to setting it to zero. If that's needed by the package user, a
function with a different name needs to be implemented instead.
Similarly for removexattr(), we wrap around and explicitly zero out the
options provided. We do so for interoperability with the linux variant.
If options are needed by the package user, a function with a different
name needs to be implemented instead.

Add ErrnoName and SignalName to get errno and signal name strings from
syscall.Errno and syscall.Signal values, respectively.
This repurposes the errors and signals vars (because they are not used
within x/sys/unix currently) and turns them into slices of struct,
containing errno/signal number, name and description. ErrnoName and
SignalName can then be trivially implemented using sort.Search.
Renaming errors to errorList additionaly allows to avoid package aliases
for the errors package.

By simply rearranging the logic, we avoid the overhead of a superfluous
call to getsockopt. For, if p is already non empty, there's no point
in having to check if we need to attach dummy payload. This has
performance benefits when using send/recvmsg for high speed
communications.
