misc: extend getpw to take uid as an argument (#3523)

File system operations may return uid and gid values, which we may want
to pretty-print. We already have the code for getting information for
the current user, so just need to add a parameter to make it exposed for
every user. We expose information about groups in a similar manner also.

win,fs: fix readlink errno for a non-symlink file (#3719)

In Node.js, fs.readlink() on a non-symlink file used to throw an UNKNOWN
error on Windows. This change maps ERROR_NOT_A_REPARSE_POINT to
UV_EINVAL, so that now it throws EINVAL just like other platforms.

This is handled explicitly in `fs__readlink`, since elsewhere it might
map to EPERM instead (such as in `link`).

linux: handle cpu hotplugging in uv_cpu_info() (#3861)

On Linux, CPUs can come online or go offline while uv_cpu_info() is busy
gathering data. Change uv_cpu_info() in the following ways:

1. Learn online CPUs from /proc/stat

2. Get the model name from /proc/cpuinfo when it has a matching CPU,
or default to "unknown"

3. Get speed from /sys/devices/system/cpu/cpu%u/cpufreq/scaling_cur_freq
when it exists, or default to 0

Before this commit, libuv read the speed from /proc/cpuinfo but that
reports the base frequency, not the actual frequency. My system has
two cores running permanently at 3.6 GHz but libuv thought all 12 ran
at 2.2 GHz.

build: drop qemu-alpha from ci matrix (#3848)

As of recent, the fs_partial_read and fs_partial_write tests reliably
fail on that architecture.

An upgrade from Ubuntu 20.04 to 22.04 on the CI machines is suspected,
not any changes in libuv itself.

Perhaps it's possible to work around it in the tests but as Alpha is a
dead architecture, it doesn't seem worthwhile to sink time in that.
Let's remove it from the CI matrix instead.

win: fix fstat for pipes and character files (#3811)

Calling uv_fs_fstat for file types other then disk type was resulting in
error on Windows while it was retrieving data on Linux. This change
enables getting fstat for pipes and character files on Windows with data
fetched being as reasonable as possible.

A simple test is also added to check this behavior on all platforms. It
uses stdin, stdout and stderr. uv_fs_fstat needs to pass with disk files
pipes and character files (eg. console).
