ending iterators.

88646061e0 libcamera: utils: Use internal secure_getenv() implementation
The secure_getenv() call is not provided by all C libraries. Support
this feature by implementing our own version.

0e1a809525 libcamera: utils: Use internal basename implementation.
Differing implementations of basename() exist, some of which may modify
the content of the string passed as an argument.

The implementation of basename() is trivial, thus to support different
C librariese, provide our own version which accepts and returns a const
char *.

Update the call sites to use the new implementation.

576c9454cf libcamera: utils: Don't use C++17 nested namespaces
Nesting namespace names in a single namespace declaration is a C++17
feature. As libcamera depends on C++11 only, nest two separate namespace
declarations instead.

a2f095947f libcamera: utils: Implement C++14 make_unique<>()
C++14 introduces std::make_unique<>() that makes it easier to initialize
unique_ptr<> instances. As libcamera is limited to C++11, implement our
own version of the function in the libcamera::utils namespace.

edbd2059d8 libcamera: Add initial logger
The logger is based on the ostream API, allowing code to log messages in
a native way. It automatically logs the time stamp, severity level, file
name and line number.

Many important features are missing, such as logging to file, logging
classes, and log filtering based on the severity level, file name and
class.
