Davi Arnaut 0eb26fdfa8 Bug#53445: Build with -Wall and fix warnings that it generates
Apart strict-aliasing warnings, fix the remaining warnings
generated by GCC 4.4.4 -Wall and -Wextra flags.

One major source of warnings was the in-house function my_bcmp
which (unconventionally) took pointers to unsigned characters
as the byte sequences to be compared. Since my_bcmp and bcmp
are deprecated functions whose only difference with memcmp is
the return value, every use of the function is replaced with
memcmp as the special return value wasn't actually being used
by any caller.

There were also various other warnings, mostly due to type
mismatches, missing return values, missing prototypes, dead
code (unreachable) and ignored return values.

BUILD/SETUP.sh:
  Remove flags that are implied by -Wall and -Wextra.
  Do not warn about unused parameters in C++.
BUILD/check-cpu:
  Print only the compiler version instead of verbose banner.
  Although the option is gcc specific, the check was only
  being used for GCC specific checks anyway.
client/mysql.cc:
  bcmp is no longer defined.
client/mysqltest.cc:
  Pass a string to function expecting a format string.
  Replace use of bcmp with memcmp.
cmd-line-utils/readline/Makefile.am:
  Always define _GNU_SOURCE when compiling GNU readline.
  Required to make certain prototypes visible.
cmd-line-utils/readline/input.c:
  Condition for the code to be meaningful.
configure.in:
  Remove check for bcmp.
extra/comp_err.c:
  Use appropriate type.
extra/replace.c:
  Replace use of bcmp with memcmp.
extra/yassl/src/crypto_wrapper.cpp:
  Do not ignore the return value of fgets. Retrieve the file
  position if fgets succeed -- if it fails, the function will
  bail out and return a error.
extra/yassl/taocrypt/include/blowfish.hpp:
  Use a single array instead of accessing positions of the sbox_
  through a subscript to pbox_.
extra/yassl/taocrypt/include/runtime.hpp:
  One definition of such functions is enough.
extra/yassl/taocrypt/src/aes.cpp:
  Avoid potentially ambiguous conditions.
extra/yassl/taocrypt/src/algebra.cpp:
  Rename arguments to avoid shadowing related warnings.
extra/yassl/taocrypt/src/blowfish.cpp:
  Avoid potentially ambiguous conditions.
extra/yassl/taocrypt/src/integer.cpp:
  Do not define type within a anonymous union.
  Use a variable to return a value instead of
  leaving the result in a register -- compiler
  does not know the logic inside the asm.
extra/yassl/taocrypt/src/misc.cpp:
  Define handler for pure virtual functions.
  Remove unused code.
extra/yassl/taocrypt/src/twofish.cpp:
  Avoid potentially ambiguous conditions.
extra/yassl/testsuite/test.hpp:
  Function must have C language linkage.
include/m_string.h:
  Remove check which relied on bcmp being defined -- they weren't
  being used as bcmp is only visible when _BSD_SOURCE is defined.
include/my_bitmap.h:
  Remove bogus helpers which were used only in a few files and
  were causing warnings about dead code.
include/my_global.h:
  Due to G++ bug, always silence false-positive uninitialized
  variables warnings when compiling C++ code with G++.
  Remove bogus helper.
libmysql/Makefile.shared:
  Remove built-in implementation of bcmp.
mysql-test/lib/My/SafeProcess/safe_process.cc:
  Cast pid to largest possible type for a process identifier.
mysys/mf_loadpath.c:
  Leave space of the ending nul.
mysys/mf_pack.c:
  Replace bcmp with memcmp.
mysys/my_bitmap.c:
  Dead code removal.
mysys/my_gethwaddr.c:
  Remove unused variable.
mysys/my_getopt.c:
  Silence bogus uninitialized variable warning.
  Do not cast away the constant qualifier.
mysys/safemalloc.c:
  Cast to expected type.
mysys/thr_lock.c:
  Silence bogus uninitialized variable warning.
sql/field.cc:
  Replace bogus helper with a more appropriate logic which is
  used throughout the code.
sql/item.cc:
  Remove bogus logical condition which always evaluates to TRUE.
sql/item_create.cc:
  Simplify code to avoid signedness related warnings.
sql/log_event.cc:
  Replace use of bcmp with memcmp.
  No need to use helpers for simple bit operations.
sql/log_event_old.cc:
  Replace bmove_align with memcpy.
sql/mysqld.cc:
  Move use declaration of variable to the ifdef block where it
  is used. Remove now-unnecessary casts and arguments.
sql/set_var.cc:
  Replace bogus helpers with simple and classic bit operations.
sql/slave.cc:
  Cast to expected type and silence bogus warning.
sql/sql_class.h:
  Don't use enum values as bit flags, the supposed type safety is
  bogus as the combined bit flags are not a value in the enumeration.
sql/udf_example.c:
  Only declare variable when necessary.
sql/unireg.h:
  Replace use of bmove_align with memcpy.
storage/innobase/os/os0file.c:
  Silence bogus warning.
storage/myisam/mi_open.c:
  Remove bogus cast, DBUG_DUMP expects a pointer to unsigned
  char.
storage/myisam/mi_page.c:
  Remove bogus cast, DBUG_DUMP expects a pointer to unsigned
  char.
strings/bcmp.c:
  Remove built-in bcmp.
strings/ctype-ucs2.c:
  Silence bogus warning.
tests/mysql_client_test.c:
  Use a appropriate type as expected by simple_command().
