1. alloc_sess will pick driver according to setup.para.task_type & alg,
   will reuse task_type & alg from init2 if no setup.para to compatible with v2
   will reuse setting.driver to compatible with v1
2. alloc_sess will add drivers to sched.drv[]
3. poll_ctx will poll all drivers in sched.drv[]
4. sw and hw will reuse common resources: sched, pool and ctxs.
5. Only hw will request real ctxs.

sw has no hw_ctx, but still need ctx_id to get pool msg
for multi-threads. so use op_ctx taking info like ctx_id
and mode: sync/async.

In order to simulate cpu instruction accelerator, this patch adds
zlib drv, which does not require accelerator at all.
So may not require wd_xxx_init, and ctx and sched which relates
to queue.

Btw, zlib is required.
yum install zlib-devel
apt-get install zlib1g-dev

Will use hisi_zlib to test adapter, so let UADK_ALG_SOFT register to uadk

sw and hw will share common resources like ctxs and pool.
sw may works on platform no accerator dev, or has dev but
no ctx, or sw driver has no op.
Ignore these error as normal cases.

User want to choose sve or ce instruction explicitly,
so modify wd_request_drv to request drv via para
alg_task_type
