Don't HANDLE_EINTR(close). Either IGNORE_EINTR(close) or just close.

Browse source 
It is incorrect to wrap close in HANDLE_EINTR on Linux.

Unnecessary #includes of eintr_wrapper.h are also removed. The variable naming
within the macro is also updated per Chromium r178174.

einter_wrapper.h contains a non-mechanical change. Mechanical changes were
generated by running:

sed -E -i '' \
    -e 's/((=|if|return|CHECK|EXPECT|ASSERT).*)HANDLE(_EINTR\(.*close)/\1IGNORE\3/' \
    -e 's/(ignore_result|void ?)\(HANDLE_EINTR\((.*close\(.*)\)\)/\2/' \
    -e 's/(\(void\) ?)?HANDLE_EINTR\((.*close\(.*)\)/\2/' \
    $(grep -rl HANDLE_EINTR.*close . --exclude-dir=.svn)

sed -E -i '' -e '/#include.*eintr_wrapper\.h"/d' \
    $(grep -EL '(HANDLE|IGNORE)_EINTR' \
        $(grep -Elr '#include.*eintr_wrapper\.h"' . --exclude-dir=.svn))
