Peter Rajnoha 06ce9b4e42 log: separate output and make it possible to use given FDs ...

Currently, the output is separated in 3 parts and each part can go into
a separate and user-defined file descriptor:

  - common output (stdout by default, customizable by LVM_OUT_FD environment variable)
  - error output (stderr by default, customizable by LVM_ERR_FD environment variable)
  - report output (stdout by default, customizable by LVM_REPORT_FD environment variable)

For example, each type of output goes to different output file:

  [0] fedora/~ # export LVM_REPORT_FD=3

  [0] fedora/~ # lvs fedora vg/abc 1>out 2>err 3>report

  [0] fedora/~ # cat out

  [0] fedora/~ # cat err
    Volume group "vg" not found
    Cannot process volume group vg

  [0] fedora/~ # cat report
    LV   VG     Attr       LSize   Layout     Role       CTime
    root fedora -wi-ao----  19.00g linear     public     Wed May 27 2015 08:09:21
    swap fedora -wi-ao---- 500.00m linear     public     Wed May 27 2015 08:09:21

Another example in LVM shell where the report goes to "report" file:

  [0] fedora/~ # export LVM_REPORT_FD=3
  [0] fedora/~ # lvm 3>report

  (in lvm shell)
  lvm> vgs

  (content of "report" file)
  [1] fedora/~ # cat report
    VG     #PV #LV #SN Attr   VSize  VFree
    fedora   1   2   0 wz--n- 19.49g    0

  (in lvm shell)
  lvm> lvs

  (content of "report" file)
  [1] fedora/~ # cat report
    VG     #PV #LV #SN Attr   VSize  VFree
    fedora   1   2   0 wz--n- 19.49g    0
    LV   VG     Attr       LSize   Layout     Role       CTime
    root fedora -wi-ao----  19.00g linear     public     Wed May 27 2015 08:09:21
    swap fedora -wi-ao---- 500.00m linear     public     Wed May 27 2015 08:09:21
