Upgrade to expat 2.2.5.
From `Changes`:
Release 2.2.5 Tue October 31 2017
Bug fixes:
#8 If the parser runs out of memory, make sure its internal
state reflects the memory it actually has, not the memory
it wanted to have.
#11 The default handler wasn't being called when it should for
a SYSTEM or PUBLIC doctype if an entity declaration handler
was registered.
#137 #138 Fix a case of mistakenly reported parsing success where
XML_StopParser was called from an element handler
#162 Function XML_ErrorString was returning NULL rather than
a message for code XML_ERROR_INVALID_ARGUMENT
introduced with release 2.2.1
Other changes:
#106 xmlwf: Add argument -N adding notation declarations
#75 #106 Test suite: Resolve expected failure cases where xmlwf
output was incomplete
#127 Windows: Fix test suite compilation
#126 #127 Windows: Fix compilation for Visual Studio 2012
#33 #132 tests: Mass-fix compilation for XML_UNICODE_WCHAR_T
#129 examples: Fix compilation for XML_UNICODE_WCHAR_T
#130 benchmark: Fix compilation for XML_UNICODE_WCHAR_T
#144 xmlwf: Fix compilation for XML_UNICODE_WCHAR_T; still needs
Windows or MinGW for 2-byte wchar_t
#9 Address two Clang Static Analyzer false positives
#59 Resolve troublesome macros hiding parser struct membership
and dereferencing that pointer
#6 Resolve superfluous internal malloc/realloc switch
#153 #155 Improve docbook2x-man detection
#160 Undefine NDEBUG in the test suite (rather than rejecting it)
#161 Address compiler warnings
Version info bumped from 7:6:6 to 7:7:6

Release 2.2.4 Sat August 19 2017
Bug fixes:
#115 Fix copying of partial characters for UTF-8 input
Other changes:
#109 Fix "make check" for non-x86 architectures that default
to unsigned type char (-128..127 rather than 0..255)
#109 coverage.sh: Cover -funsigned-char
Autotools: Introduce --without-xmlwf argument
#65 Autotools: Replace handwritten Makefile with GNU Automake

option USE_libbsd=ON to use arc4random_buf of libbsd
#74 CMake: Add -fno-strict-aliasing only where supported
#114 CMake: Always honor manually set BUILD_* options
#114 CMake: Compile man page if docbook2x-man is available, only

Release 2.2.3 Wed August 2 2017
Security fixes:
#82 CVE-2017-11742 -- Windows: Fix DLL hijacking vulnerability
using Steve Holme's LoadLibrary wrapper for/of cURL
Bug fixes:
#85 Fix a dangling pointer issue related to realloc
Other changes:
Increase code coverage
#91 Linux: Allow getrandom to fail if nonblocking pool has not
yet been initialized and read /dev/urandom then, instead.
This is in line with what recent Python does.
#81 Pre-10.7/Lion macOS: Support entropy from arc4random
#86 Check that a UTF-16 encoding in an XML declaration has the
right endianness
#4 #5 #7 Recover correctly when some reallocations fail
Repair "./configure && make" for systems without any
provider of high quality entropy
and try reading /dev/urandom on those
Ensure that user-defined character encodings have converter
functions when they are needed
Fix mis-leading description of argument -c in xmlwf.1
Rely on macro HAVE_ARC4RANDOM_BUF (rather than __CloudABI__)
for CloudABI
#100 Fix use of SIPHASH_MAIN in siphash.h
#23 Test suite: Fix memory leaks

Release 2.2.2 Wed July 12 2017
Security fixes:
#43 Protect against compilation without any source of high
quality entropy enabled, e.g. with CMake build system;
commit ff0207e6076e9828e536b8d9cd45c9c92069b895
#60 Windows with _UNICODE:
Unintended use of LoadLibraryW with a non-wide string
resulted in failure to load advapi32.dll and degradation
in quality of used entropy when compiled with _UNICODE for
Windows; you can launch existing binaries with
EXPAT_ENTROPY_DEBUG=1 in the environment to inspect the
quality of entropy used during runtime; commits

* 73a5a2e9c081f49f2d775cf7ced864158b68dc80
[MOX-006] Fix non-NULL parser parameter validation in XML_Parse;
resulted in NULL dereference, previously;
commit ac256dafdffc9622ab0dc2c62fcecb0dfcfa71fe
Bug fixes:
#69 Fix improper use of unsigned long long integer literals
Other changes:
#73 Start requiring a C99 compiler
#49 Fix "==" Bashism in configure script
#50 Fix too eager getrandom detection for Debian GNU/kFreeBSD
#52 and macOS
#51 Address lack of stdint.h in Visual Studio 2003 to 2008
#58 Address compile warnings
#68 Fix "./buildconf.sh && ./configure" for some versions
of Dash for /bin/sh

with multiple CMakeLists.txt files
#72 CMake: Resolve mistaken executable permissions
#76 Address compile warning with -DNDEBUG (not recommended!)
#77 Address compile warning about macro redefinition
