mmap() and msync() were already described as not leading to
inotify events. This patch adds munmap(). I created and executed
a test to verify this.

This example of the usage of the inotify API shows the

as polling and reading from the inotify file descriptor.

Example from https://sourceware.org/glibc/wiki/Locales
After modifying a locale, make sure it compiles, and install it to a
temporary directory for testing:
unset LC_ALL
LOCALE=fi_FI
export I18NPATH=$HOME/locale-test/
export LOCPATH=$HOME/locale-test/
mkdir -p $LOCPATH
localedef --no-archive -f localedata/charmaps/UTF-8 -i localedata/locales/$LOCALE $I18NPATH/$LOCALE.UTF-8
LC_TIME=$LOCALE.UTF-8 locale -ck LC_TIME

lang_term reflects ISO 639-2/T (terminology) codes, while
lang_lib reflects ISO 639-2/B (bibliographic) codes.
lang_term is preferred over lang_lib codes for locale names.
There are 20 specific ISO 639-2/B codes.

Michael Kerrisk pointed me to alignment issues which may
arise when reading misaligned integers.
On some systems integer values can only be read if they are
correctly aligned. Other system have a lower performance when
reading from or writing to misaligned memory positions.
Therefore, the buffer used to call read(2) for a fanotify
file descriptor should have the same alignment as
struct fanotify_event_metadata.
Due to the casting to char* inside the macros
FAN_EVENT_OK and FAN_EVENT_NEXT we can use any
data structure for the buffer.
With the patch an array of struct fanotify_event_metadata is
used as buffer which seems a natural choice to ensure proper
alignment.
It should be remembered that the offset between events is given
by field event_len and iterating over the array may not be
allowable in future. Instead the macros should be used.

The elements of the array sys_errlist are also const.
Also, it is probably not desirable to pretend that errno.h defines
