EMSI handshake FTSC-0088 compliant, protocol_order, EMSI TZUTC

CHANGES

@@ -228,9 +228,25 @@ Alexey Khromov (zx@zxalexis.ru)
  + Added pre-init debugging (primarily of config readout) to stderr by -v
    option. Vanished out errorful calls to "log" and "debug" before log and
    debug files initialization.
- + As of bison is default yacc for (almost) every foss system - fix
-   warning of yacc compliance (delete -y flag in Makefile.in)
  + Fixed build on 64-bit systems (amd64 and aarch64)
  + Initially added config options incpkt_flag and incbdl_flag to raise
    up flag-driven tosser manipulation
    
+0.24.2
+ + Fixed environment variables while executing external programs
+   on handshake or session end
+ + Fixed flags working on arcmail/netmail recieve
+ 
+0.25
+ + EMSI handshake logic reworked to comply with EMSI-II std (FTSC-0088)
+ + New option: proto_order - dezired protocol order for outgoing calls 
+   in EMSI session handshake
+   EMSI-II-compliance works as follows:
+    * if both (caller and callee) expose EII flag - selected proto
+    will be first in caller compat.options compatible with callee
+    * if caller is EMSI-I-compliant and does not show EII flad - 
+    selection by callee internal order from compatible with caller
+ + Changed ifcico protocol port hardcoded to num and not name from
+   /etc/services line (as of abscence of latter)
+ + Config example reworked to include new options
+ + New option: emsi_send_tz - to send TZUTC EMSI-handshake part.

 Для нормальной работы вам нужно отредактировать конфигурационные файлы

+Bforce при ИСХОДЯЩИХ звонках использует файлы блокировки порта модема,
+при несовпадении каталога или невозможности создания файла
+mgetty сбросит модем во время звонка. 
+Поэтому настоятельно рекомендуется проверить права на папку /var/lock
+и то, на какой ФС она расположенв.
+Современные системы имеют тенденцию к применению /var/lock как ссылки
+на /run/lock, а ФС /run монтируется и создается на tmpfs при каждой 
+загрузке с помощью systemd-tempfiles.
+Для изменения поведения необходимо создать файл в /etc/tempfiles.d/, 
+совпадающим (за исключением части имени -part) c именем файла в 
+/usr/lib/systemd/systemd-tempfiles.d.
