The VCARD_ATR_PREFIX macro adds a prefix of 6 characters only.
pcsc_scan was complaining before the patch:
+ Historical bytes: 56 43 41 52 44 5F 4E 53 53
ERROR! ATR is truncated: 2 byte(s) is/are missing

vscclient needs to call socket_init() for portability.
Moving to osdep.c since it has no internal dependency.

It is needed to give that flag to the linker as well, but latest
libtool 2.4.2 still swallows that argument, so let's pass it with

Why "let it through" if it's too long?

I know windows doesn't like too short, but no idea about too long. Haven't seen this in practice yet (well, we control the other end too, but I saw no reason to fail it at this point).

This overrides whatever debug value is set on the corresponding devices
from the command line, and is meant to ease the usage with any
management stack. For libvirt you can set environment variables by
extending the dom namespace, i.e:
<domain type='kvm' id='3' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
<qemu:commandline>
<qemu:env name='QEMU_CCID_PASSTHRU_DEBUG' value='4'/>
<qemu:env name='QEMU_CCID_DEBUG' value='4'/>
</qemu:commandline>
</domain>

5. adds three debugging environment variables: QEMU_CCID_PASSTHRU_DEBUG, QEMU_CCID_DEBUG and LIBCACARD_DEBUG
The reason for using those is that it makes it easier to use with libvirt, which already supports environment variables on qemu machines via an extended xml namespace.
Additionally, please ignore 26/26, I'll drop it, didn't mean to send it. (it's a nop anyway).
