THRIFT-3288 c glib build unit tests with all warnings enabled
**Note:** This pull request includes the changes from request #576 (to fix
THRIFT-3285), which should be applied first.
These changes
- Update the C (GLib) unit tests' Makefile so
- Compiler-flag variables are used correctly according to automake's
documentation and
- The same comprehensive set of compiler warnings is enabled as is used
for the C++ unit tests, and
- Update the unit tests so they build without generating any compiler
warnings.
As a bonus, the final commit gently refactors several compiler functions
changed as part of this work, primarily to improve readability and to more
consistently use helper functions for formatting rather than embed formatting
directly in the output.

c_glib: Library: Use AM_CPPFLAGS for include paths, not AM_CFLAGS
This follows the description of the two variables in the automake
documentation.

c_glib: Library: Build with all warnings enabled
This matches the settings ("-Wall -Wextra -pedantic") used to build
the C++ library.

c_glib: Library: Build without compiler warnings
These changes allow the C (GLib) library to be built without
warnings from the compiler, even with extra compiler warnings
enabled. The changes involve
- Moving variable declarations to the top of every code block,
- Using unions instead of type-punning to follow strict-aliasing
rules,
- Replacing variable-length array declarations with arrays
allocated on the stack (using g_newa and g_alloca),
- Casting void pointers to a suitably sized data type before
performing arithmetic on them,
- Replacing C++-style ("//") comments with C-style equivalents,
and
- Removing an errant semicolon and comma.

Makefile.am: Enable warnings, improve automake-variable use
This change
- Enables the same comprehensive set of warnings ("-Wall -Wextra
-pedantic") specified for the unit tests for C++ and
- Changes the use of automake variables (e.g. AM_CPPFLAGS) to more
closely match their intended use, as specified in the automake
documentation.

c_glib: Compiler: Don't mix declarations and code
This change moves variable declarations to the top of code blocks
in the generated code, resolving a number of "ISO C90 forbids mixed
declarations and code" warnings when building the unit tests.

c_glib: Compiler: Silence unused-parameter warnings
This change modifies the generated class and interface initializers
so they don't generate "unused parameter" warnings when compiled.

c_glib: Build unit tests without compiler warnings
These changes allow the unit tests for C (GLib) to build without
compiler warnings, even with additional warnings enabled. They
include
- Disabling string-function optimizations when glibc is used, as
these produce compiler warnings when a string function is used
within a call to assert ();
- Remove the "LL" suffix (added in C99) from 64-bit integer
literals;
- Replace C++-style ("//") comments with C-style equivalents;
- Remove unused constant declarations that generated warnings;
and
- Mark (or remove, from main ()) unused function parameters.

c_glib: Compiler: Gently refactor functions
This change gently refactors a handful of recently modified
functions to
- Wrap lines at 80 columns,
- Improve readability (making the layout of the compiler's source
code more closely match that of the code it's generating),
- Use more consistently the indent_up/indent_down and
scope_up/scope_down helper functions rather than embedding
formatting characters directly, and
- Improve slightly the formatting of the generated code.
