#27176: Assigning a string to an year column has unexpected results
#26359: Strings becoming truncated and converted to numbers under STRICT mode

Problems: 
1. storing a string to an integer field we don't check 
   if strntoull10rnd() returns MY_ERRNO_EDOM error.
   Fix: check for MY_ERRNO_EDOM.
2. storing a string to an year field we use my_strntol() function.
   Fix: use strntoull10rnd() instead.

  #27176: Assigning a string to an year column has unexpected results
  #26359: Strings becoming truncated and converted to numbers under STRICT mode
    - Field_num::get_int() method introduced. It converts a string to integer
      then check errors and bounds.
    - similar Field_tiny::store(const char...),  Field_short::store(const char...),
      Field_medium::store(const char...), Field_long::store(const char...)
      rewritten, now they just call Field_num::get_int() then store value returned.
    - Field_num::check_int() simplified.
    - Field_year::store(const char...) now uses strntoull10rnd() and properly checks
      errors returned.
sql/field.h:
  Fix for bugs
  #27176: Assigning a string to an year column has unexpected results
  #26359: Strings becoming truncated and converted to numbers under STRICT mode
   - check_int() moved to Field_num.
   - get_int() introduced.
