The warnings are emitted when a translation unit attempts to reference
a function whose availability is newer than the deployment target.

Patch from Erik Chen <erikchen@chromium.org>.
Add MapInsertOrReplace<>() to insert a key-value pair into a map if the
key is not already present, or replace the existing value for key if the
key is present. The original value can optionally be returned to the
caller in this case.
Map insertions now use either MapInsertOrReplace<>() or
std::map<>::insert() directly.
Use MapInsertOrReplace<>() when the map should be updated to contain a
mapping from a key to a value regardless of whether the key is already
present.
Use std::map<>::insert() to insert a mapping from a key to a value
without replacing any existing mapping from a key, if present. If it is
important to know whether an existing mapping from a key was present,
use the returned std::pair<>.second. If it is important to know the
existing value, use the returned std::pair<>.first->second.
This change has a slight positive impact on performance.

CXX_LIBRARY_VERSION is irrelevant, because the only C++11 library
feature of any concern is whether numeric_limits’ min() and max() are
declared constexpr.
Crashpad is C++11-only as far as the language is concerned, and the
comment doesn’t need to call it out explicitly because static_assert()
is always available.

Unfortunately VS2013's support of C++11 is partial. It supports the
extended union definition, but does not fully support constexpr.
So, update some locations where CXX_LIBRARY_VERSION is used where
toolchain support is lacking. It works correctly in the locations
where std::is_standard_layout is used.

This only came up in one location, PointerVector.
A template alias is superior to inheritance, which doesn’t provide full
type equivalence and doesn’t automatically inherit non-default
constructors.

This includes the StringToNumber() function, both int and unsigned int variants.
Similar functionality is available in base, but it is unsuitable for
applications where a number’s base may be determined based on an "0x" or
"0X" prefix (hexadecimal) or an "0" prefix (octal).
