possible after OSv has crashed.

std::streambuf<char> is defined as an "extern template", which means it is
instantiated in the library, not at the point-of-use, in order to reduce
object size and compilation time.

One of its member functions, std::basic_streambuf::seekpos(...) has a
parameter whose type depends on mbstate_t; this embeds the type name into
the mangled function name.

On Linux, mbstate_t is a typedef for __mbstate_t, so the latter type name
is embedded into the mangled function name.  On osv, there is no such typedef,
so mbstate_t is embedded.  This causes lookup to fail when loading a shared
object that uses streambufs.

Fix by defining mbstate_t in the same way as glibc.

optind is a global variable that is expected to be zero-initialized by

Unlike tls for the main module, which simply offsets fs:0, shared object
use an indirection scheme since each module gets its own tls base address,
which needs to be found (and initialized) via __get_tls_addr()

Implement __get_tls_addr() and the associated relocation and storage
management.

Currently we search the entire vma list while looking for a range.  This
is less than optimal.

Define a vma::addr_compare function object that can be used as comparator
with boost::rbtree::equal_range(), and use that to search for both bounds
simultaneously.

The system classloader should have classes which were
specified in the command line using -cp/-classpath/-jar.
Before this change only runjava.jar was included.

System class loader is queried explicitly by
java.util.logging framework to lookup classes
configred in logging properties file.

To solve this problem a custom system classloader
is set when starting JVM. It delegates to the application
classloader created when java program was started.

It also handles the case when a new java application
is started within the same JVM. Such application
should have its own view of system classes. However
we are able to install only one system classloader
per JVm. To solve this we start each java application
in a separate thread and use InheritableThreadLocal
to hold the application class loader which should be
used as system class loader view for the thread family.
